Question

A BLUEPRINT 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.

Answer 1

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
