the perimeter of an isosceles triangle is 32 cm.the ratio of the equal side to its base is 3:2.find the area of the triangle

Equal side = 3x

so perimeter = 3x + 3x +2x = 32

8x = 32

x =4

Equal side = 3 x 4 = 12

base = 2 x 4 = 8

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

area of an isosceles triangle = bh_b/2

base = 8 x 12/2 = 96/2 = 48
