In an isosceles triangle, the perimeter is 36 cm and the base is 10 cm. Find the length of the side.

The perimeter is the sum of the lengths of all sides of a geometric shape.

An isosceles triangle is a triangle in which the sides are equal in size.

1. Knowing the perimeter and length of the base, we calculate the sum of the two lateral sides:

36 – 10 = 26 cm.

2. Since the sides are equal, we calculate the length of each of them, dividing their sum by two:

26: 2 = 13 cm.

Answer: The length of the side in a triangle is 13 centimeters.
