Area of Equilateral Triangle
Perimeter
`(P) = 3 a`
Area
`(A) = sqrt(3)/4 a^2`
Example :
I know that for a equilateral triangles Side = 6 . From this find out Area of the equilateral triangles.
`"Here " a = 6" (Given)"`
`"We know that,"`
`"Perimeter" = 3 * a`
` = 3 * 6`
` = 18`
`"We know that,"`
`"Area" = sqrt(3)/4 * a^2`
` = 1.732/4 * 6 * 6`
` = 15.5885`
