Area of Composite Shapes

Interactive practice questions

Consider the given shape.

The composite figure consists of two rectangles, labeled A and B. Rectangle A is placed on top of Rectangle B. Rectangle A is longer than Rectangle B. The length of rectangle A measures $9$ $cm$ . The width of rectangle A measures $1$ $cm$ . The width of rectangle B measures $5$ $cm$ . Rectangle A extends $4$ $cm$ beyond Rectangle B on the left side. Rectangle A extends $2$ $cm$ beyond Rectangle B on the right side. The length of rectangle B, $3$ $cm$ , is not explicitly labeled.

a

Determine the area of rectangle $B$B.

b

Hence calculate the total area of the composite shape.
