The length of room = 10 ft
the width = 14 ft
the height = 12 ft
there are 4 walls and the floor
one wall has area = 10*12=120 ft^2
4 walls has area = 4*120=480 ft^2
the floor has area = 10*14=140 ft^2
total area of walls and floor = 480+140= 620 ft^2
- so bc. we know that each tile is 1 foot long and 1 foot wide so what mean an area of 1 ft^2 and the total area equal 620 ft^2 so this mean that Jamie will need 620 tiles
