The area of the trapezoid is the product of the height and the average of the two bases: 
<span>30 (25 + 33)/2 = 30 (58)/2 = 30 (29) = 870 square yd. </span>

<span>But we want to exclude the area of the fountain. </span>
<span>Since it's circular its area is π times the square of its radius, or 16π square yd. </span>

<span>So the area of the park, excluding the fountain, is </span>
<span>870 - 16π square yd, </span>
<span>or about 820 square yd.</span>

jok3333 [9.3K]
He would have four fields. Since the area of 1/2 milex1/2 mile is 1/4, and 1x1 is 1, so 4 fields make up the land.
