The area of one lateral face of a right pyramid with an equilateral triangular base is 75 square meters. If the slant height is 25 meters, what is the length of the side of its base, in meters?
If the lateral face is 75 m^2 and the slant height is 25 m, we can find the length of one side of the base as
75 = (1/2) base * 25 multiply by 2 on both sides
150 = base * 25 divide both sides by 25
6 (m) = base length
