Answer:
219.96 yd²
Step-by-step explanation:
Calculate the area (A) of the trapezoid using the formula
A = [tex]\frac{1}{2}[/tex] h(a + b)
where a, b are the parallel bases and h is the height
here h = 11.7, a = 21.8 and b = 15.8
A = [tex]\frac{1}{2}[/tex] × 11.7(21.8 + 15.8)
= 0.5 × 11.7 × 37.6 = 219.96 yd²
