Question

A square plot of land has a building 80 ft long and 60 ft wide at one corner. The rest of the land outside the building forms a parking lot. If the parking lot has area 7,300 ft2, what are the dimensions of the entire plot of land?

Answer 1

The area of the building is 80 * 60 = 4,800 ft2.

The area of the entire plot of land is 4,800 +  7,300 = 12,100 ft2.

Since the plot is square, each side has the length of √12,100 = 110 ft.

So, the dimensions of the entire plot are 110 ft by 110 ft.
