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
