Question

The ratio of equal side to the base of an isosceles triangle is 3:1. If the perimeter of

the triangle is 28 cm. find its area​

Answer 1

Answer:

47.04

Step-by-step explanation:

let one side be=x

and base be=3x

So,

perimeter of isosceles triangle=2a+b

28=2x+3x

28=5x

28/5=x

5.6=x

Now

First side=5.6=second side

and base=3*5.6=16.8

Now area of isosceles triangle

area of triangle=bh/2

y=16.8*5.6/2

y=47.04
