    Step-by-step explanation:

    (a) Perimeter = Sum of all the sides

    = 4 cm + 2 cm + 1 cm + 5 cm = 12 cm

    (b) Perimeter = Sum of all the sides

    = 23 cm + 35 cm + 40 cm + 35 cm = 133 cm

    (c) Perimeter = Sum of all the sides

    = 15 cm + 15 cm + 15 cm + 15 cm = 60 cm

    (d) Perimeter = Sum of all the sides

    = 4 cm + 4 cm + 4 cm + 4 cm + 4 cm = 20 cm

    (e) Perimeter = Sum of all the sides

    = 1 cm + 4 cm + 0.5 cm + 2.5 cm + 2.5 cm + 0.5 cm + 4 cm = 15 cm

    (f) Perimeter = Sum of all the sides

    = 4 cm + 1 cm + 3 cm + 2 cm + 3 cm + 4 cm + 1 cm + 3 cm + 2 cm + 3 cm + 4 cm +

    1 cm + 3 cm + 2 cm + 3 cm + 4 cm + 1 cm + 3 cm + 2 cm + 3 cm = 52 cm

    Step-by-step explanation:

    1-Hey !! Side of square = 10 cm. Therefore, Perimeter of square = 4 × ( Side ) = 4 × 10 = 40 cm.

    2-The perimeter is equal to 4s, where s is the length of the sides. So 4s = 40 m, and therefore s = 10 m. So the length of each side

    3- Area=L x w 15 X 15

    =225 cm sq.

    perimeter is sum of all side

    =15+15 + 15 +15What is the area and perimeter of 15cm by 15cm?

    The figure is 15 cm by 15 cm means that it is a square where each side has length s=15 cm. Its area A is

    A=s2=15 cm×15 cm=225 cm2.

    The perimeter p, that is, the sum of the lengths of the four sides is

    p=4×s=4×15 cm=60 cm.

    Area=L x w 15 X 15

    =225 cm sq.

    perimeter is sum of all side

    =15+15 + 15 +15

    =60 cm.

    How do you find the area of a heptagon with sides measuring 15cm each?

    Let’s divide it in 7 triangles, each with one vertex in the center of the heptagon, and 2 in the closest vertices of it. From here we are to find the angles between the base and sides of each triangle. The angle near the common vertex is 360/7=51+3/7 degrees. The two other angles are equal, so they

    The area of a square is 121 sq. m. What is its perimeter?

    Friends..! Area of square = (sides)^2 Area of the square = 121 sq m. Thus (sides)^2 = 121 sq m. Sides = √121 Sides = √11 × 11 Sides= 11 metres Now Perimeter of square = 4 (side) = 4 × 11 metres = 44 metres Answer the perimeter of the square is 44 metres

    What is perimeter and area in math?

    In classical, standard, geometry, the perimeter of an enclosed figure is the length of its boundary. For example, a circle’s perimeter is P = 2pi*r, where r is its radius. Of course, as the figure becomes more irregular, its perimeter usually becomes harder to calculate. For instance, if the circle

    If the area of a square is 400 m sq, what will be the sides and perimeter?

    A= L^2 Where L is length of the side 400=L^2 》》》》》 square root L= 20 all sides of square are 20 m P = 4L =4(20) =80m

    How are perimeter and area related?

    The relationship is fairly weak. With a given amount of perimeter available, there is a maximum area that can be enclosed (attained by a circle), but there’s no positive minimum area. Given a certain area that is to be enclosed, there is a minimum necessary perimeter (corresponding to the circle) but

    The perimeter of a square is double the perimeter of a rectangle. The area of the rectangle is 240 sq cm. What is the area of the square?

    Let length of each side of a square is a cms , its perimeter is 4.a cms. and length and breadth of a rectangle are x and y cms respectively, its perimeter is 2(x+y) cms. , Acordingly:- 4.a= 2×{2.(x+y)}. or. a= (x+y)…………….(1) Area of square = a^2 = (x+y)^2…………..(2) Area of the rectangle = x×y = 240. …………….

    Triangle ABC is right angled at B, the length of AC=17cm, BC=15cm, what is the length of AB?

    If you have a right angled triangle this can be calculated using Pythagoras’ theorem. If corner B is the right angle then no matter where you put A or C. AC at 17cm must be the hypotenuse (longest side). Pythagoras theorem usually uses ABC as the names of the sides but to save confusion with the point

    If a square has a perimeter of 28 cm, what is the area of the square?

    Perimeter of square equals 4L Where L is the length of side of the square. Hence, 4L = 28 L = 28÷4 L = 7 Area of square equals L*L Area of square = 7*7 = 49 Area of square equals 49(cm^2)

    A rectangle has an area of 90 cm 2 and a perimeter of 46 cm. What are its dimensions?

    18 centimetres is it’s length and 5 centimetres is it’s breadth. Perimeter is 2(l+b) = 46 centimetres l+b = 46/2 = 23. Area is 90 square centimetres, so one of it’s dimensions should be either 10 or 5 centimetres. If 10 is one measure other measure is 13 centimetres. Area will be 130 square centimetres

    What is the area of a square with a perimeter of 16?

    16 sqare units side =4 Area of a sqare = 4^2

    How do you find the area of a heptagon with sides measuring 15cm each?

    The area of a square is 121 sq. m. What is its perimeter?

    What is perimeter and area in math?

    If the area of a square is 400 m sq, what will be the sides and perimeter?

    How are perimeter and area related?

    The perimeter of a square is double the perimeter of a rectangle. The area of the rectangle is 240 sq cm. What is the area of the square?

    Triangle ABC is right angled at B, the length of AC=17cm, BC=15cm, what is the length of AB?

    If a square has a perimeter of 28 cm, what is the area of the square?
