Question

Each leg of an isosceles triangle is 4 meters longer than the base. the perimeter of the triangle is 26 meters. find the lengths of the side.

Answer 1

Answer: Sides will be 10cm ,10cm ,6cm.

Step-by-step explanation:

We have given that

In isosceles triangle ,

Let the base be x

Let the equal sides of isosceles triangle be x+4

Perimeter means the sum of boundary

∴
`Perimeter= x+x+4+x+4= 26\\3x+8=26\\3x=26-8\\3x=18\\x=(18)/(3)\\x=6 cm`

So, the equal sides will be
`x+4=6+4=10cm`

and the base = 6cm.
