The equation for finding the area of a rectangle is as follows:

Let l = length of the rectangle

Let w = the width of the rectangle

$$A_{\text{rect.}}=lw$$

If you never know how to start a problem, utilizing a formula is probably the way to go. Plug in the known values into the equation and solve for the missing one:

 $$117=l*9$$ Solve for the width by dividing by 9 on both sides of the equation $$13m=l$$ Of course, don't forget your units of measure!
