First we will need to convert 75 to cm
75 m = 0.75 cm
0.75 * 3.5 * 2 (since there are two of these) = 5.25 m^2
5 * 0.75 * 2 = 7.5 m^2
5 * 3.5 * 2 = 35 m^2
7.5 + 35 + 5.25 = 47.75 m^2
So, A.
75 m = 0.75 cm
0.75 * 3.5 * 2 (since there are two of these) = 5.25 m^2
5 * 0.75 * 2 = 7.5 m^2
5 * 3.5 * 2 = 35 m^2
7.5 + 35 + 5.25 = 47.75 m^2
So, A.
