Answer 2

Answer:

Semi perimeter of an equilateral triangle is 12 cm.

Step-by-step explanation:

Given:

Side of equilateral triangle (a) = 8 cm.

As we know that;

Semi perimeter of an equilateral triangle = 3a/2

                                                                   = (3 × 8)/2

                                                                   = 24/2 =12 cm.
