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!
