    This is problem of ratio and proportion. to solve this, fisrt is calculate the convertion factor.

    so the house is 30 feet in actual and 4 in wide on drawing

    30 feet / 4 in = 7.5 feet / inso in every inch in the drawing is equivalent to 7.5 feet on actual.

    1.2 in (7.5 ft / in) = 9 ft

    1.6 in (7.5 ft / in) = 12 ft
