Question

What is the area of an equilateral triangle with sides of 8?

Answer 1

The formula for area of an equilateral triangle is:
`sqrt3/4 (side)^2`

the side =`8 cm`
(assuming the unit to be in cm)

area = `sqrt3/4 (side)^2`
`= 0.433 xx (8)^2`
`= 0.433 xx 64`

area `approxcolor(blue)(27.71 cm^2`
