Solution: - Calculate the area of the large rectangle: 8 ft × 5 ft = 40 sq ft. - Calculate the area of the cut-out rectangle: 3 ft × 2 ft = 6 sq ft. - Subtract the cut-out area: 40 sq ft – 6 sq ft = 34 sq ft. Example 2: Composite Figure with a Circle and Rectangle Problem: Find the total area of a figure composed of a rectangle measuring 10 m by 4 m and a semicircle with a radius of 2 m attached to the top of the rectangle. Solution: - Area of rectangle: 10 m × 4 m = 40 sq m. - Area of full circle: π × r² = 3.14 × 2² = 3.14 × 4 ≈ 12.56 sq m. - Area of semicircle: ½ × 12.56 ≈ 6.28 sq m. - Total area: 40 + 6.28 ≈ 46.28 sq m. --- Tips for Teachers and Students Using the Worksheet For Teachers: - Incorporate visual aids to help students Area Of Composite Figures Worksheet 6 understand decomposition. - Design problems that progressively increase in difficulty. - Encourage students to label all parts and measurements carefully. - Use real-world scenarios to make problems relatable.
