Question

Find the area of an equilateral triangle with sides 24cm each?

Answer 1

A ≈ 249.42 cm²

Explanation:

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

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

given s = 24 , then

A =
`(24^2√(3) )/(4)`

=
`(576(√(3)) )/(4)` ( cancel 576 and 4 by 4 )

= 144 ×
`√(3)`

≈ 249.42 cm² ( to 2 decimal places )
