Mary covered her kitchen floor with

10 tiles. The floor measures 6 feet long

by 5 feet wide. The tiles are each 3 feet

You have to write an equation though not solve it.

long and w feet wide.

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
