Answer
The perimeter is 15 inches.
Solution
In an equilateral triangle, all sides are the same length. Since one side is given as 5 inches, the other two sides are also 5 inches each. To find the perimeter, add the lengths of all three sides:
Perimeter = 5 in + 5 in + 5 in = 15 in
So, the correct answer is 15 in.

In an equilateral triangle, all three sides are of equal length. So, if one side measures 5 inches, the other two sides also measure 5 inches each. To find the perimeter, simply add the lengths of all three sides: 5 in + 5 in + 5 in = 15 in. So, the perimeter of the equilateral triangle is 15 inches! It's a neat little geometry fact that can make you feel like a math wizard when you solve it. Keep this in mind as you tackle other types of triangles, where side lengths may vary!
