Question

The base of an isosceles triangle is12cm and its perimeter is 32cm find its area

Answer 1

The base is 12cm
And its perimeter is 32 then it's area is 48 cmsq

Answer 2

let other two equal side of the triangle be x
therefore, 2x + 12 = 32
2x = 32 -12
2x = 20
x = 20/2
x = 10 cm
area = 10× 12/2
= 120/2
= 60 sq cm
