    Answer:

    in right angled triangle hypotenuse is biggest side

    since its isoseles , the lenght of its 2 other legs are equal

    perimeter = 41cm

    hypotenuse = 17 cm

    let the other 2 sides be x and x = 2x

    17 + 2x = 41

    x = (41 – 17)/2

    x = the respective lenght of other 2 sides = 12

    area = 1/2 * base *hieght

    area = 1/2 * 12 * 12

    area = 1/2 *144

    area = 72 cm^2

    hope this helps 🙂
