Question

Find the perimeter of an equilateral triangle whose side is:

$8cm$

Answer 1

Given side of an equilateral triangle $=8cm$

The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape.

Perimeter of an equilateral triangle $=3\times side$

$$\begin{gathered} =3\times 8 \\ =24cm \end{gathered}$$

Hence perimeter of an equilateral triangle is $24cm$
