Answer to Problem 31AYU

The double tennis court is 78 feet long and 36 feet width.

Explanation of Solution

Given:

A regulation doubles tennis court has an area of 2808 square feet. If it is 6 feet longer than twice its width.

Calculation:

2808 = ( 2w + 6 )w

2 w 2  + 6w  2808 = 0

Therefore the positive root of w = 36 .

So the length is 78 and width is 36.

That is the double tennis court is 78 feet long and 36 feet width.
