Think about the shape shown below.

A composite shape is made up of two rectangles labeled $A$A and $B$B. Scale lines indicate the dimensions of the composite shape. Rectangle $A$A is vertically oriented with a width measuring $13$13 $m$m and a length measurement of $4$4 $m$m. Rectangle $B$B has a given length measuring $6$6 $m$m, while the width is not labeled. Rectangle B is attached to the right side of the rectangle A and positioned such that its bottom side is $3$3 $m$m from the bottom of rectangle $A$A and its top side is $5$5 $m$m from the top of rectangle $A$A.
