Question

Devin wants to have equal amounts of room on all four sides of his ping pong table. A 5ft by 9ft table is placed in the center of a rectangular room that has an area of 221 square feet. What is the width of the clear space Devin will have on all sides of his table?

Answer 1

Let x be the width of the clear space on all side of the table.
\[\text{Solve }[(5+2x)(9+2x)=221,x]\]x = 4 feet
