To determine the total area of the flat roof on a building including the overhang, it's important to first calculate the dimensions of the roof considering the overhang.

The building dimensions are 30 feet by 66 feet. An overhang of 2 feet 6 inches must be added to each dimension. Since there are two sides to the building where the overhang occurs (one on each end), you will add twice the overhang to each dimension.

2 feet 6 inches is equivalent to 2.5 feet. Therefore, for the length of 66 feet, the overhang adds 2.5 feet on each end, resulting in an additional 5 feet. Thus, the new length is:

66 feet + 5 feet = 71 feet

Similarly, for the width of 30 feet, the overhang adds 2.5 feet to each end, resulting in another 5 feet. Hence, the new width is:

30 feet + 5 feet = 35 feet

To find the total area of the roof, multiply the adjusted dimensions together:

Total area = Length x Width

Total area = 71 feet x 35 feet = 2485 square feet

This calculation confirms the total area of the flat
