Answer 2

Answer:

Perimeter of the equilateral triangle is 36 cm.

Step-by-step explanation:

Given:

Length of each side of an equilateral triangle= 12cm.

As we know,

Perimeter of a triangle = sum of three side of the triangle

Perimeter of an equilateral triangle = 12+ 12+12 (since all sides are equal of an equilateral triangle )

                                                          = 36 cm.
