Sean is his dad build a tiled walkway in their backyard. the walkway will be 60 feet long and 2 feet wide. the local hardware store sells tiles which are 2 by 2 feet and come in boxes of 6.
how many boxes of tiles do they need?

The answer is 5 boxes. First we have to do 60 x 2 to find out the area of the walkway (120 ft). Then since the tiles are 2 by 2 feet and come in 6 boxes we do, 2 x 2 to find the area of 1 tile,which is 4 ft, then we multiply that by 6 to find out the total amount of tiles which is 24. We then divided 120 by 24 to find out how much boxes we will need which is 5. Hope that helped :)
