Area of Composite Figures Worksheets
Use labeled dimensions to calculate area of composite figures and explain the units.
Before you begin
Read labeled dimensions and coordinates. Recall multiplication facts and length units.
Worked example
An L-shaped floor is made from two non-overlapping rectangles. The upper rectangle is 5 m by 7 m. The lower rectangle is 8 m by 4 m. Find the total area.
- Upper area: 5 × 7 = 35.
- Lower area: 8 × 4 = 32.
- Add the two areas; no part is counted twice.
Answer: 67 m²
Check your result using the method in the example before moving to the next question.
