ser-zykov [4K]
29,600 ft².

Here is how you find it:

First find the area of the piece of land, so multiply 140 feet by 220 feet. You should get 30,800 ft².

Next find the area of the building, so do 40 feet times 30 feet, and you should get 1,200 ft².

To find the remaining area, do 30,800-1,200. You should get 29,600 ft², the remaining area for the park.

Hope this helps!
