Question

an equilateral Triangle if its perimeter is 22.5 CM Q find the length of one side of
​

Answer 1

Answer:

X+x+x=22.5

3x=22.5

X=22.5/3

X=7.5

Answer 2

Given :-

Perimeter of the equilateral triangle = 22.5 cm

To Find :-

The length of one side of the equilateral triangle.

Analysis :-

Substitute the value provided in the question in the formula of perimeter of a triangle.

Then you can easily find the side of each.

Solution :-

We know that,

• s = Side
• p = Perimeter

By the formula,

$\underline{\boxed{\sf Perimeter \ of \ triangle=3a}}$

Given that,

Perimeter (p) = 22.5 cm

Substituting their values,

22.5 = 3a

a = 22.5/3

a = 7.5 cm

Therefore, the length of each side is 7.5 cm.
