An architect drew the blueprint for a new office building. He used a scale in which 1 inch represents 7.5 feet. The floor of an office in the building will have actual dimensions of 18 feet by 16 feet. What will the dimensions on the blueprint be?
we know that scale factor=1 in/7.5 ft scale factor=measurements on the blueprint/measurements in the actual measurements on the blueprint=[measurements in the actual*scale factor] so
for 18 ft measurements on the blueprint=[18 ft*(1 in/7.5 ft)-----> 2.4 in
for 16 ft measurements on the blueprint=[16 ft*(1 in/7.5 ft)-----> 2.1 in
the dimensions on the blueprint are 2.4 in x 2.1 in
