The area of the trapezoid is the product of the height and the average of the two bases:
30 (25 + 33)/2 = 30 (58)/2 = 30 (29) = 870 square yd.
But we want to exclude the area of the fountain.
Since it's circular its area is π times the square of its radius, or 16π square yd.
So the area of the park, excluding the fountain, is
870 - 16π square yd,
or about 820 square yd.
30 (25 + 33)/2 = 30 (58)/2 = 30 (29) = 870 square yd.
