Question

A triangle has a priemeter of 39 units . Each side of this triangle is the same length. What is the length of one side of the triangle in units

Answer 1

This is easier to understand with a picture...

We know that a triangle has 3 sides right?

Well, if the perimeter is 39 and there are 3 sides you would divide 39 by the 3 sides

39/3=13

Therefore, one side of the triangle would equal 13
