Peterson will need 39 more tiles to completely cover the kitchen floor
Step-by-step explanation:
Given dimensions of kitchen are:
12 feet and 7 feet
In order to find the number of tiles for the kitchen, we have to first find the area of the kitchen
So,
Area of kitchen:
[tex]A = 12 * 7\\ = 84\ square\ feet[/tex]
The area is 84 square feet which means 84 one square foot tiles are needed to completely cover the floor of kitchen.
As Peterson already has 45 tiles, so the more tiles she will need is:
[tex]84-45 = 39\ tiles[/tex]
Hence,
Peterson will need 39 more tiles to completely cover the kitchen floor
