what dimensions (in inches) should be shown on the blueprint?

Question

On a blueprint, a 1 in. scale corresponds to 7 ft. To show a room with actual dimensions 35 ft wide by 16 ft long, what dimensions (in inches) should be shown on the blueprint?

width and length

Answer 1

The 1 in. to 7 ft. scale says that for every 7 ft. in actual dimensions, the blueprint should show 1 in. So actual 35 ft. wide is 5 in. wide on the blueprint. And actual 16 ft. long is 2-2/7≈2.28 in. long on the blueprint.
