Question

Use the formula for the area of a trapezoid , where A is area, b1 and b2 are the length of the bases, and h is the height, to answer the question. How many square feet of grass are there on a trapezoidal field with a height of 75 ft and bases of 125 ft and 81 ft?  

Answer 1

A = h(b1 + b2)/2 = 75(125 + 81)/2 = 75(206)/2 = 75(103) = 7725 sq. ft
