Answer 2

Concept

An equilateral triangle is special four sided figure where all sides are equal.

Given

An equilateral triangle whose side is 8cm.

Find

Area of the equilateral triangle with side length 8cm.

Solution

In a equilateral triangle all sides are equal ,

The area of the triangle A = $\frac{\sqrt{3}}{2} a^{2}$, where a = 8cm.

A=$\frac{\sqrt{3} }{2}$ x 8x8 cm^{2}

A=$\sqrt{3}/2$ × 64 cm^{2}

A= 16$\sqrt{3}$cm^{2}.

The area of equilateral triangle with side length 8cm is A= 16$\sqrt{3}$cm^{2}.
