Isosceles Triangle: The triangle in which the two sides of a triangle are equal, then the angles opposite to equal sides are also equal.

Perimeter of triangle = Sum of all sides.

As the property of a triangle states that in an isosceles triangle two sides of a triangle are equal.

As two sides of a triangle are given as \[15\] and \[22\], respectively.

We can fix either the two equal sides as \[15\] and the third side is \[22\] (or) the two equal sides as \[22\] and the third side is \[15\].

The sides of triangle can be either $15,15,22$ or $15,22,22$

Perimeter of the triangle = Sum of three sides of a triangle

Perimeter of the triangle = $15+22+22=59$ or $15+15+22=52$

Therefore, the possible values of the perimeter are $59\text{ or 52}$ .
