Question

1. a builder needs to tile a 7 - foot - by - 8 - foot room with one - foot square tiles. how many tiles will she need? type your answer into the box. ___ tiles

Explanation:

Step1: Calculate room area

The room is 7 - foot - by - 8 - foot. The area of a rectangle is $A = l\times w$, so $A=7\times8 = 56$ square feet.

Step2: Determine number of tiles

Each tile is 1 - foot by 1 - foot, so the area of each tile is 1 square foot. To find the number of tiles needed, divide the room area by the tile area. $\frac{56}{1}=56$.

Answer:

56
