Answer:
l x w / s
Step-by-step explanation:
Floor is covered with 10 tiles
Floor measurement: 6 feet length x 5 feet width
Area covered by floor = 6 x 5 = 30 square feet
Since there are 10 tiles, each tile = 30/10 = 3
Hence in terms of equation
if the length of the tile is l and the width w
If s is used to represent the size of each tile
number of tiles needed is l x w / s
