Mary covered her kitchen floor with 10 tiles. the floor measures 6 feet long by 5 feet wide. the tiles are each 3 feet long and w feet wide?

1 feet wide

Step-by-step explanation:

We first need to find the area of the floor.

6*5=30

Then we divide the area by the number of kitchen tiles to get the area of each tile.

30/10=3

After this, we set up a L x W = A equation to solve for w.

3*w=3

3w=3

w=1
