Question

c) In an equilateral triangle, the sum of three sides is 132 cm. write this in equation form .​

Answer 1

Let one of its side be x cm .. all the 3 sides of equilateral triangle are equal hence. .. all sides are x

sum of three sides = 132 cm

x+x+x= 132

3x=132.

this is the required equation....

after solving x= 44cm

Answer 2

Step-by-step explanation:

To find:

In an equilateral triangle, the sum of three sides is 132 cm. write this in equation form .​

Given:

In an equilateral triangle, the sum of three sides is 132 cm

We know that the three sides of an equilateral triangle are equal

Solution:

Let,the one side of the triangle be x cm

Thus,In equation form:

(x+x+x)=132

Answer:

(x+x+x)=132
