**DrBob222**, Tuesday, January 19, 2010 at 4:34pmYour first job should be to determine the dimensions of the floor.

Let X = width, then

X + 2 = length.

The area is 168; therefore,

X(X+2) = 168 which expands to

X^2 + 2X - 168.

Solve that for X and X+2 then look to see how much smaller the rug should be. Post your work if you get stuck.
