Answer:

• 296 m²

Solution:

Area of upper figure = 2(lw + lh + wh) = 2lw + 2lh + 2wh

• l = 4 m
• w = 5 m
• h = 4 m

Solve:

• 2[(4 m × 5 m) + (4 m × 4 m) + (5 m × 4 m)]
• 2[20 m² + 16 m² + 20 m²]
• 2[56 m²]
• 112 m²

Area of lower figure = 2(lw + lh + wh) = 2lw + 2lh + 2wh

• l = 8 m
• w = 5 m
• h = 4 m

Solve:

• 2[(8 m × 5 m) + (8 m × 4 m) + (5 m + 4 h)]
• 2[40 m² + 32 m² + 20 m²]
• 2[92 m²]
• 184 m²

Area of Composite Figure = upper area + lower area

• 112 m² + 184 m²
• 296 m²
