Andre owned a 1/4 acre lot. He wanted to construct a 120' x 80' tennis court on the lot. How many square feet will remain uncovered after he builds the tennis court?

The area of the tennis court is computed by multiplying the dimensions given,

A = 120' x 80'

A = 9600 ift

Then, we convert the area in ft² to acres,

A = (9600 in²) (2.3 x 10^-5 / 1 in²)

A = 0.24 acre

The portion of land remaining is,

A of remaining = 0.25 acre - 0.24 acre

= 0.1 acre

The remaining portion is for Andre's studies.

This, 0.1 ft² is equal to the 4% of the given area of the court.
