Question

Find the area of an equllateral triangle with a side of 6 Inches.

6V3 in 2
9/3 in 2
4.5/3 in 2

Answer 1

9
`√(3)` in²

Explanation:

The area (A) of an equilateral triangle can be calculated using

A =
`(s^2√(3) )/(4)` ← s is the length of side

Here s = 6, thus

A =
`(6^2√(3) )/(4)` =
`(36√(3) )/(4)` = 9
`√(3)` in²
