Question 4
Write True or False and justify your answer:

The area of the equilateral triangle is $20\sqrt{3}c{m}^2$ whose each side is 8cm.

Answer 1

False
Given
The side of an equilateral triangle = 8cm.
Area of an equilateral triangle $=\frac{\sqrt{3}}{4}(Side{)}^2$
$=\frac{\sqrt{3}}{4}\times (8{)}^2=\frac{64}{4}\sqrt{3}[\because side=8cm]$
$=16\sqrt{3}c{m}^2$
