Question

The perimeter of an equilateral triangle is 360m. Find the each side of triangle

Answer 1

Perimeter = side +side +side

Let length of side be x

x+x+x=360m
3x=360m
x=360/3
x= 120

Answer 2

Answer:

The side of an equilateral triangle is 120 cm .

Step-by-step explanation:

Given information,

Perimeter of equilateral triangle is 360cm.

We have to find out the side of an equilateral triangle.

Equilateral triangle means the triangle which is having all equal sides.

By finding the length of one side we can find out the length all sides.

As we know that,

The perimeter of equilateral triangle = 3S

Where,

S is the side of an equilateral triangle.

By putting given values in the formula

360 = 3 S

$S = \frac{360}{3}$

S = 120

Hence,

The side of an equilateral triangle is 120 cm .
