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
