Question

The base of an isosceles triangle is 7cm.The perimeter of the triangle is 29cm.Find the length of the equal sides.​

Answer 1

Answer:

11 cm

Step-by-step explanation:

Let each of the equal sides be x.

Perimeter = Sum of all sides

Given Perimeter = 29 cm

=> 2x = 29 - 7

=> 2x = 22

=> x = 11

Hence, the length of the equal sides are 11 cm.
