Answer 1

Answer:

perimeter of a triangle= a+b+c

As it is equilateral triangle, a=b=c

So,

180=a+a+a

180=3a

a=60cm

Answer 2

The side of an equilateral triangle is 60 cm. (c).

Given,

An equilateral triangle.

The perimeter of the triangle = 180 cm.

To Find,

The side of the equilateral triangle.

Solution,

We know that the perimeter of an equilateral triangle = 3 x side.

⇒ Perimeter = 3 x side

⇒ 180 cm = 3 x side

⇒ side = 180/3 cm

⇒ side = 60 cm

Hence, the side of an equilateral triangle is 60 cm.
