To find out how many square feet of grass are on the trapezoidal field, we can use the formula for the area of a trapezoid:
A = (b1 + b2) / 2 * h
Given that the height (h) is 75 ft, the length of the first base (b1) is 125 ft, and the length of the second base (b2) is 81 ft, we can substitute these values into the formula:
A = (125 + 81) / 2 * 75
Simplifying the equation:
A = 206 / 2 * 75
A = 103 * 75
A = 7725 ft^2
Therefore, there are 7,725 square feet of grass on the trapezoidal field.
Use the formula for the area of a trapezoid upper A equals h left-parenthesis Start Fraction b subscript 1 baseline plus b subscript 2 baseline over 2 End Fraction right-parenthesis, 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?
