Question

The base of an isosceles triangle is 24 cm and its area is 192 cm^2 . Find its perimeter.

Answer 1

Explanation:

Area of Traingle=1/2×b×h

192cm²=1/2×24×h

192cm²=12×h

h=192/12

h=16cm

Hypotenuse ²=Base²+Altitude ²

Hypotenuse ²=12²+16²

Hypotenuse ²=144+256

Hypotenuse ²=400

Hypotenuse =20cm

Perimeter=20+20+24

=64cm
