    if 0.5" = 12'

    0.5"x10 = 12'x10

    5" = 120'

    (1/2) [in] rep 12 [ft].  10*(1/2) [in] rep 10*12 [ft].  5 [in] rep 120 [ft]. Answer = 5 [in].

    You can set this up as a Ratio and Proportion problem.

    Real feet : drawing inches  :: real feet : drawing inches

    Real . . . . Drawing

    -------- = --------------

    Real . . . . Drawing

    12 feet . . . .0.5 inches

    ---------- = ------------------

    120 feet = . x inches

    1) Cross multiply

    12x = (120)(0.5)

    2) Solve the parentheses

    12x = 60

    3) Divide both sides by 12 to isolate x

    x = 5

    Answer:

    On the scale drawing, the side of 120 feet is represented by a line 5 inches long.

    ----------------------

    You can also figure it out by logic.

    On the scale drawing, a 12-foot section of wall is represented by a line that is 1/2 inch long.

    You need 10 of these half-inches to represent a line 120 feet long.

    Ten pieces, each 1/2 an inch long, add up to a line that is 5 inches long

    (same answer)

    How many 12 feet sections are in 120 feet

    120 / 12 = 10

    The scale drawing will need 10 of the 1/2 inch sections

    10 * 1/2 = 5

    5 inches <––––––

    It’ll be 5 inch by 5 inch. 

    1 inch = 24 ft. 

    120 ft/24 ft  = 5
