The perimeter of an isosceles triangle is 24. The base is 4. Find the side.

It is known from the condition that the perimeter of an isosceles triangle is 24 cm. It is also known that the base of a triangle is 4 cm. In order to find the side, recall the definition of an isosceles triangle.

An isosceles triangle is a triangle whose sides are equal to each other.

And in order to find the perimeter of an isosceles triangle, we use the formula:

P = 2a + b;

Let’s make the equation:

2a + 4 = 24;

2x = 24 – 4;

2x = 20;

x = 20: 2;

x = 10 cm the length of the side of the triangle.
