Answer:
1. Area = 52 in²
Solution
Area of Rectangle and a triangle:
A = LW + 1/2bh
A = (13 in × 4 in) + 1/2(4 in × 2 in)
A = 48 in² + 4 in²
A = 52 in²
2. Area = 29 m²
Area of a square and a rectangle
solution:
A = LW + s²
A = (10 m × 2m) + (3m)²
A = 20 m² + 9m²
A = 29 m²
3. Area = 77 cm²
Area of a triangle and a square
Solution:
A = 1/2bh + s²
A = 1/2(7 cm × 8 cm) + (7 cm)²
A = 28 cm² + 49 cm²
A = 77 cm²
4. Area = 73.12 cm²
Area of a semicircle and a triangle
solution:
A = 1/2bh + 3.14(r²)/2
A = 1/2(8 cm × 12 cm ) + 3.14(4 cm)²/2
A = 48 cm² + 25.12 cm²
A = 73.12 cm²
