Question

How do you calculate the perimeter of an equilateral triangle?

Answer 1

Compute the perimeter of an equilateral triangle.

As we know, the perimeter of an equilateral triangle is the sum of its three sides of the triangle.

Where, $a$ are the sides of the triangle.

1. An equilateral triangle is one with equal sides and an equal angle on all sides.
2. The internal angles of the equilateral triangle are also the same, that is, $60$ degrees.

Area of an equilateral triangle $=\frac{\sqrt{3}}{4}{a}^2$

3. The perimeter of an Equilateral triangle is,

$P=3a$

Hence, the perimeter of an equilateral triangle is calculated by the formula, $P=3a$.
