Eliminate the fractions by multiplying by least common multiple.
4,9,12 all go into 36 evenly. Multiply entire equation by 36.

36/4 = 9
36/9 = 4
36/12 = 3

New equation looks like:
9(w-1) +4(w+1) = -3(w+1) \\  \\ 9w -9 +4w +4 = -3w -3  \\  \\ 9w +4w+3w = -3 +9 -4 \\  \\ 16w = 2 \\  \\ w = \frac{2}{16} = \frac{1}{8}

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>
