Answer 1

This is the answer..

Perimeter is 6 cm

Side is 2 cm

Answer 2

Given:

Height of equilateral triangle = √3unit

To Find

Find the side and perimeter of equilateral triangle

Steps

As we know that

Height = √3/2a

Let " a " be the side of equilateral triangle

Height of equilateral triangle = √3/2a

➢√3 = √3/2a

➢ 1 = 1/2a

➢ 2a = 1

➢ a = 1/2 unit

Perimeter equilateral triangle

➳ 3a

➳ 3 × 1/2 = 3/2 unit

Hence, the side of equilateral triangle is 1/2unit and its perimeter is 3/2unit
