Question

Given an equilateral triangle. If the perimeter is 24 Then what is the length of one side?

Answer 1

8 because an equilateral triangle has 3 equal sides. So if each side is 8, then added together the perimeter is 24.

Answer 2

An equilateral triangle have the same length on all sides.

Let x = the length on one side of the equilateral triangle
Then 3x = the perimeter around the equilateral triangle

3x = 24

Divide both sides by 3.

3x / 3 = 24 / 3
x = 8

So, the length of one of the sides is 8 units long.
