Question

The lengths of two sides of an isosceles triangle are $15$ and $22$ respectively. What are the possible values of perimeter?

Answer 1

An isosceles triangle has two sides of equal length. We have two sides of 15 and 22 .

So, third side must be either 15 or 22.

Then possible perimeter are $15+15+22=52$ or $15+22+22=59$

As perimeter is the sum of the sides.
