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?

Answer 1

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.

Answer 2

6465 yd^2, do we divide by 4 now?

Answer 3

6464 yd^2*

Answer 4

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
