 .

Example Question #342 : Plane Geometry

Find the perimeter of an equilateral triangle that has a side with a length of 9cm.

Possible Answers:

Correct answer:

Explanation:

The formula to find the perimeter of a triangle is

where a, b, and c are the lengths of the sides.  When looking at equilateral triangles, we know that all lengths are equal.  Therefore, we know that each side is equal to 9cm.  So,

 

Example Question #343 : Plane Geometry
