Question

A park is 300 yds by 500 yds. There is a 4 wide foot walking path going around the entire perimeter of the park. The rest of the park is green space. How much green space is there in the park?

since the 4-yd path is on both sides and both ends,
(300 + 8)(500 + 8) - 300*500 = ? yd^2

unless the path is 4 feet wide, in which case you need to change it some.
Math
6465 yd^2, do we divide by 4 now?
Math
6464 yd^2*

Oops. I added the path to the dimensions; I should have subtracted. The green area is inside the path.

(300 - 8)(500 - 8) = 143664 yd^2

Thank you oobleck.
