Ablueprint of a building gives a scale of 1inch=8feet. if the blueprint shows the building sitting on a rectangle with dimesions 16 inches by 25 inches, what is the actual area of the rectangle on which the building sits? express your answer in sqaure feet.

To answer this case, you need to convert the blueprint measurement into the actual measurement by multiplying it with the scale. In this case, the scale is 8ft/1 inch. Then the calculation would be:
Rectangle actual length = rectangle blue print length * blue print scale
Rectangle actual length = 25 inch * 8ft/inch= 200ft

Rectangle actual width = rectangle blue print width* blue print scale
Rectangle actual width = 16 inch * 8ft/inch= 128ft

Rectangle actual area= Rectangle actual length * Rectangle actual width = 200ft * 128 ft= 25600ft square

The answer would be option 4
