The perimeter of an equilateral triangle is 39 meters. In meters, how long is one side of the triangle?
Explanation
An equilateral triangle has sides that are the same length. Then, to find the length of one side, you only need to divide the perimeter by 3.
The perimeter of an equilateral triangle is 
Explanation
Since an equilateral triangle has sides that are all the same, divide the perimeter by 
An equilateral triangle has a perimeter of 
Explanation
Because an equilateral triangle has three sides that are the same length, divide the given perimeter by 3 to find the length of each side.
The perimeter of an equilateral triangle is 
Explanation
Since an equilateral triangle has three equal sides, divide the perimeter by 
The perimeter of an equilateral triangle is 
Explanation
Since an equilateral triangle has three equal sides, divide the perimeter by 
The perimeter of a equilateral triangle is 
Explanation
Since all three sides are equal in an equilateral triangle, we can just divide the perimeter by 3 to find a side length.
The perimeter of an equilateral triangle is 
Explanation
Because all the sides in an equilateral triangle are equal, we can just divide the perimeter by 3 to find the length of a side.
