A rectangular room is 4 yards long and 5 yards wide. Lucas is covering the floor with tiles that are 1 square foot. How many tiles will he need?

He would need 60 because 4*5 = 20 wich is the area in yard and 3 feet are in 1 yard so your gonna multiply 20 times 3 to get 60 (1) foot tiles

The first thing you need to do is convert the width and length to feet, since it is currently in yards, but Lucas is buying 1 foot tiles. Since one yard equals 3 feet, you would multiply the sides by 3 to convert the side lengths to feet. This would give you the dimensions in feet which are 12 by 15. Then, since the problem is looking for the amount of tiles to cover the rectangular room, you would multiply the dimensions 12 and 15, to get you to your answer 180 tiles.
