Question

Find the area of the equilateral triangle whose sides are 4 yd.

Answer 1

s=6 so area =4• square root of 3

Answer 2

Area of a equilateral triangle =
`4√(3)` square yards

Explanation:

side of the equilateral triangle = 4 yd

Area of a equilateral triangle =
`(√(3))/(4) * side^2`

side = 4

Area of a equilateral triangle =
`(√(3))/(4) * 4^2`

=
`4√(3)`

Area of a equilateral triangle =
`4√(3)` square yards
