Question

The length of each of two equal sides of an isosceles triangle is 4m less than twice the length of the third side. Find the dimensions of the triangle if it's perimeter is 57m. ​

Answer 1

Answer:

let the length of the equal side be x

the length of the third side be y

x + 4 = 2y

2y + y = 57

solving the equation, we get

x = 22

y = 13

So,

the dimensions of the triangle :- 22, 22, 13
