The sides of a equilateral triangle measure 12cm.what is the perimeter of the triangle?

Answer 1

Hi.

In an equilateral triangle, as the name implies, all the sides are equal in length.

You find perimeter by adding all the sides.

The formula for perimeter is 3a where a = the length of the side.

3(12) = 36 cm

The perimeter of the triangle is 36 cm.
