Question

A tennis court is surrounded by a fence so that the distance from each boundary of the tennis court to the fence is the same, x feet. If the tennis court is 78 feet long and 36 feet wide, which expression gives the area of the entire surface inside the fence?

Answer 1

Given the information, we have the following:

since the distance from each boundary of the tennis court to the fence is the same (x feet), then we have:

therefore, the expression that gives the are of the entire surface inside the fence is A=(36+2x)(78+2x)
