Answer 1

Length of equilateral triangle, a = 12 cm

Perimeter of an equilateral triangle = 3 × a

= 3 × 12

= 36 cm

Answer 2

Answer:

Hence the perimeter of the equilateral triangle is 36 cm.

Step-by-step explanation:

According to the information provided in the question.

It is stated in the preceding question that,

The presented information is side of an equilateral triangle is 12 cm.

We need to find the perimeter of equilateral triangle.

The formula of perimeter of the equilateral triangle is as bellow,

$P=3a$

Where a is the side of the triangle,

Substitute the value of side that is 12cm in the above equation we get,

$P=3\times 12\\P=36cm$

Hence the side of the equilateral triangle is 36 cm.
