Answer:
B. 250 ft²
Step-by-step explanation:
We have two squares S × S and four rectangles S × L.
S = 5 ft and L = 10 ft.
The area of a square:
[tex]A_s=(5)(5)=25\ ft^2[/tex]
The area of a rectangle:
[tex]A_r=(5)(10)=50\ ft^2[/tex]
The Surface Area:
[tex]S.A.=2A_s+4A_r[/tex]
Substitute:
[tex]S.A.=2(25)+4(50)=50+200=250\ ft^2[/tex]
