Question

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

Answer 1

let equal side is x
and other side is y
perimeter of isosceles triangle: 2x+y=32.......(1)

2nd condition,
x/y=3/2
2x=3y
2x-3y=0............(2)
by solving equation (1)and (2)
we got
y= 8 and x= 12 ..
