    Given:

    ☆PQRS is a square.

    ☆PR(diagonal)=10cm

    To find:

    ☆Area of the square(PQRS)

    Solution:

    We know that ,area of a square when a diagonal is given:

    =>1/2d²

    =>1/2(10)²

    =>1/2×100

    =>50cm².

    Thus,area of the square is 50cm².

    square = PQRS

    PR = 10 cm

    NOTE: PR is the diagonal of the square

    FACT: diagonals of a square are equal

    as square is a rhombus, we can use the formula of rhombus to find the area of the square.

    1/2 * d1 * d2 = area

    1/2 * 10 * 10

    5 * 10 = 50

    therefore, the area of the square is 50cm^2
