1 foot = 12 inches
--------------------------------------------------------------------------------------------------
Find the scale:
map : actual = 9 inches : 36 feet
Convert all to the same units:
map : actual =9 inches : 432 inches
Find 1 inch on the map:
map : actual = 1 inches : 48 inches
Therefore the scale is:
map : actual = 1 : 48
--------------------------------------------------------------------------------------------------
Find the area on the map:
Length = 9 inches
Width = 32 ÷ 48 = 2/3 inches
Area = 9 x 2/3 = 6 in²
--------------------------------------------------------------------------------------------------
Answer: The area is 6 in²
