What is the area of a composite shape consisting of rectangles 5 by 4 and 3 by 4?

Explanation:
Think about the areas of the two rectangles and how they combine. Each rectangle has height 4, with widths 5 and 3. The total area is the sum of their areas: 5×4 plus 3×4, which is 20 + 12 = 32. You can also view the combined shape as one rectangle with width 8 (5 + 3) and height 4, giving 8×4 = 32. So the area is 32. The other numbers come from miscounting the overall dimensions.
