Question

9. The perimeter of an isosceles triangle is 32 cm. The ratio of one of the
equal sides to its base is 3:2. Find the area of the triangle
​

Answer 1

given that one of equal side to its base ratio is 3:2

so equal sides + base =perimeter

3x+2x +3x=32

x=32/8 =4

so sides are 12,12,8

s=(a+b+c)/2 =32/2 =16

we know that area of any triangle is

√s(s-a)(s-b)(s-c)

apply s,a,b,c sides in it u get 32√2 as answer
