PLEASE HELP ME! ALGEBRA PROBLEM!

Question

The Community Recreation Center is developing plans for a new sports facility. Community members can submit suggestions for the new facility, along with basic scale drawings of their ideas. Elena wants to include a new 15- by 30-meter basketball court in the athletic center. She is submitting a scale drawing on an 8.5- by 11-inch sheet of paper. Which scale should Elena use to create as large a drawing as possible on the paper? 

Answer 1

The length of the courts is twice its width.

The scale drawing must have the same ratio.

If she made the drawing 8.5 wide, the length must be 17 inches. Too long

If she made the drawing 11 long, the width would be 5.5 inches. Perfect.

The scale should be 11/30.
