an equilateral triangle has 3 equal sides. The name comes from latin equi meaning equal and lateral meaning side.

If one side = x + 5 , then all sides = x + 5.

Therefore the perimeter is simply the addition of (x+5) + (x+5) + (x+5), or

3x + 15

-The perimeter of a rectangle is 48 centimeters. If the length of the rectangle is 16 centimeters, find its width.

Or
