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