Solve mathematical and real-world problems involving the perimeter and area of composite figures composed of non-overlapping rectangles with whole-number side lengths.

A pool is comprised of two non-overlapping rectangles in the shape of an “L”. The area for a cover of the pool can be found by adding the areas of the two non-overlapping rectangles.

*Clarification 2: *Each rectangle within the composite figure cannot exceed 12 units by 12 units and responses include the appropriate units in word form.
