Question

A rectangular piece of land measures 140 feet by 220 feet. A building on that land occupies an area of 40 feet by 30 feet. What is the remaining area that can be used for a park?

Answer 1

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!
