Question

An equilateral triangle has a side length of 24 inches. What is its perimeter?

Answer 1

72 in.

Explanation:

Since this triangle is an equilateral triangle, all sides are equal. You only have to multiply the side you are given by 3. Doing so you get:

`24*3=72`

Thus, 72 inches is your answer.

Note: This only works for equilateral triangles. With isosceles or scalene triangles, you must have the angular quantities to do the problem.

Answer 2

`72` inches

Explanation:

The perimeter is the sum of the sides of a given shape. We know a few things about our shape:

• We have a triangle, which has `3` sides
• This is an equilateral triangle, meaning the lengths are equal
• One side is `24` inches

If all of the sides are the same, we are essentially adding

`24+24+24` to get

`72` inches

Hope this helps!
