Quite Simple & Elementary.
Monthly Rent for 500 sq. ft. = $ 875
Monthly Rent for 1 sq.ft. = 875 divided by 500 = $1.75
Floor Area covered by the couch: 4' * 9 ' = 36 sq.ft.
Monthly Rent for 36 sq.ft. = 36 times $1.75
= $ 63. ANSWER.

4x9=36 sq ft.
36/500= 0.072 decimal fraction of the apt floor of 500 sq ft covered by the couch
$875x0.072 = $63 per month for the couch's floor space
