First, we have to calculate the area of each painted rectangle:

Area of a rectangle: Length x width

Replacing with the values given:

8.2 x 6.7 = 54.94 ft2

Estimating:

8 x 7 = 56 ft2

Then multiply by the number of porch floors:

9 neighbor's floors and Vaughn's floor = 9+1 = 10

56 x 10 = 560 ft2

correct answer B.
