The base of an isosceles triangle is 16 cm, and the perimeter is more than 48 cm.

The base of an isosceles triangle is 16 cm, and the perimeter is more than 48 cm. What number can express the length of the side of the triangle?

In order to find the length of the side of an isosceles triangle, let’s remember and apply the formula to find the perimeter of an isosceles triangle.

An isosceles triangle has a base and sides that are the same length.

Since the perimeter is the sum of the lengths of the sides of any geometric figure. For an isosceles triangle, we write the perimeter as:

P = 2a + b;

a – side, b – base of the triangle.

Let us express the lateral side from the formula:

2a = P – b;

a = (P – b) / 2;

Let’s calculate:

a = (48 – 16) / 2 = 16 cm
