a floor plan has been prepared for a new building, drawn to a scale of 1/2 inch = 1 foot. A certain area is drawn to a scale of 1 foot long and 7 1/2 wide on the floor plan. the actual dimensions of theis areas in the building are?

Answer 1

Scale: 1/2 in = 1Ft. = 12 in

Ratio = (1/2)in/12in = 1/24

L = 24 * 1Ft = 24 Ft.

W = 24 * (7.5/12)Ft = 15 Ft.

Note: I assumed you mean 7 1/2 in wide.
