Question

A side of an equilateral triangle is 36yd long. What is the area of the triangle?

Answer 1

A ≈ 561.2 yd²

Explanation:

the area (A) of an equilateral triangle is calculated as

A =
`(s^2√(3) )/(4)` ( where s is a side of the triangle )

here s = 36 , then

A =
`(36^2√(3) )/(4)` =
`(1296√(3) )/(4)` = 324
`√(3)` ≈ 561.2 yd²
