Question

Use the formula for the area of a trapezoid A = h (bi+b²), 2 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

Answer:

• 7725 ft³

===================

Use the given numbers and formula to calculate the area:

• $A = h(b_1+b_2)/2$

• $A = 75(125+81)/2=75(206)/2=75(103)=7725$
