Question

the area of an equilateral is 16m^2 find the length of each side of the triangle

Answer 1

Hello user...
Here is the answer..

Given that area is 16 m sq.
We know that area of an equilateral triangle is (3^1/2)/4 *a^2

please don't be confused..^1/2 means square root...
Equating the formula with the given data.
We get a^2=37.6(approx)

So the side, a=6.1 approx...
