spet by step​

Answer 1

Step-by-step explanation:

As we know that perimeter of an equilateral triangle is 3 × side. First we will find the perimeter.

Perimeter of an equilateral triangle

= 3 × side

= 3 × 10 cm

= 30cm

Semi Perimeter means the perimeter of the half part of the equilateral triangle.

So, we will divide 30 cm by 2.

The answer will come as 15 cm.
