So first you need to add 4 to each side to get (x+5)^2=16. Next you need to take the square root of each side to get √(x+5)^2=+-√16. After that simplify to get x+5=+-4. Now subtract 5from both sides to look like x=-5+-4. Now just do x=-5+4 and x=-5-4 then solve to get x=-1 and x=-9.
Answer: 819.73 yd²
<u>Step-by-step explanation:</u>
= 
= 
= 29 * 30
= 870
= π(4)²
= 16π
≈ 50.27
Area of the park = 
= 870 - 50.27
= 819.73
