In a rectangular room 10 feet wide 40 feet long and 50 feet high there are four Windows each 30 inch by 48 inches what is the ratio of Windows Surface 2 floor area in this room?

Answer 1

area of the 4 windows
= 4(30/12)(48/12) = 40 ft^2

area of floor = 10(40) = 400 ft^2
(where does the ridiculous height of 50 ft come in ?)

ratio of window area : floor area = 40:400
= 1:10
