    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
