Looks like you trying to first find the area of a rectangle. What's the formula for the area of rectangle?

OpenStudy (scarlettfarra2000):

\[a=wl\]

OpenStudy (scarlettfarra2000):

So would it look like this? \[10^2+22^2=748\]

It is lw, but it'll be (10 + 2x)(22 + 2x) = 748 Which means you have to use the FOIL method
