Answer:
S.A. = 209.8 m²
Step-by-step explanation:
We have:
2 rectangles 4m × 3.8m
2 rectangles 3.8m × 11.5m
and 2 rectangles 4m × 11.5m
The formula of an area of a rectangle:
A = lw
l - length
w - width
Calculate:
(4)(3.8) = 15.2 m²
(3.8)(11.5) = 43.7 m²
(4)(11.5) = 46 m²
The Surface area:
S.A. = (2)(15.2) + (2)(43.7) + (2)(46) = 30.4 + 87.4 + 92 = 209.8 m²
