Consider the following figure.
A composite figure consists of two rectangular sections joined together to form an irregular L-shape. The first rectangle is positioned on top of the second rectangle. Measurements are labeled along the sides of the shape. The first rectangle has a horizontal side labeled $4$4 m, and its vertical side is labeled $x$x. The second rectangle, at the bottom, has a horizontal side of $12$12 m and a vertical side of $2$2 m. On top of the second rectangle, the distance from the left vertical side to the first rectangle is labeled $y$y. On the left side of the composite figure, the total vertical side is labeled $9$9 m.
