Question

If measure of equal sides of an isosceles triangle is 'x' cm and the other side is 8 cm, then the perimeter of the triangle is cm.

• A. 2x + 8
• B. 8x + 2
• C. 2 + x + 8

Answer 1

The correct option is A 2x + 8

Perimeter of a triangle is the sum of all its three sides.
Here, it is given that measure of equal sides is 'x' cm and the other side is 8 cm.
So, perimeter of the triangle is x + x + 8 = 2x + 8 cm.
