  1. 8‑46. Bee is tiling her kitchen floor using square tiles that are 1 foot long on each side. The rectangular floor is 13 feet by 7 feet. Homework Help ✎

    1. If she has 86 tiles, does she have enough to cover the floor? If not, how many more does she need?

    2. Does she have enough to tile just around the edges of the kitchen? If so, how many leftover tiles will she have? If not, how many more will she need? Draw a picture and show your work.

Instead of counting the tiles, use multiplication to find the area (space inside the rectangle) of the floor.

The area is the same as the number of tiles she needs. Does she have enough?

Be careful not to count the corners twice.
