If a floor area measures 280" x 360", what is the total area in square feet?

To find the total area in square feet, first, we calculate the area in square inches by multiplying the length and width of the floor area. The length is 280 inches and the width is 360 inches.

Calculating the area in square inches:

Area = Length × Width

Area = 280 inches × 360 inches

Area = 100,800 square inches.

Next, we need to convert square inches to square feet. Since there are 144 square inches in a square foot (12 inches × 12 inches), divide the total area in square inches by 144:

Area in square feet = Total area in square inches ÷ 144

Area in square feet = 100,800 ÷ 144

Area in square feet = 700.

Thus, the total area of the floor in square feet is 700 sq. ft. Making this the correct choice among the given options.
