Problema Solution
The carpet in a room, which is 13.5 ft long and 17.0 ft wide, needs to be replaced. If the carpet comes in 2 ft x 2 ft squares that each cost $1.75, how much will it cost to replace the carpet in the room?
Answer provided by our tutors
first we will find the area of the carped in a room:
A = length*width
A = 13.5*17
A = 229.5 ft^2
the carpet comes in 2 ft x 2 ft squares that each cost $1.75
229.5 : 4 = 57.375 thus we will need 58 2 ft x 2 ft squares to cover the room
indeed: 58*4 = 232 and 57*4 = 228
thus it will cost:
58*1.75 = $101.5 to replace the carpet in the room.
