Answer:

Question:-

Find the length of a side of an equilateral triangle perimeter is 72 cm.

Given :-

Figure is equilateral triangle

Perimeter of figure = 72cm

Aim :-

To find side of the triangle

Equilateral triangle:-

In a equilateral triangle, all the sides are equal

All angles are equal.

Hence, Perimeter = Side + side + side => 3 × side

Let the side be x cm.

As we know that,

3 × side = Perimeter,

substituting the values,

3 × x = 72

Transposing 3 to the RHS (Right hand side),

x = \dfrac{72}{3}x=

3

72

By reducing to the lowest terms,

x = 24

Side of the triangle = 24cm
