Question

A rectangular floor of area 30.24 m2 is going to be tiled. Each tile is rectangular, and has an area of 432 cm2. An exact number of tiles can be put into the space. How many tiles will be needed?

Answer 1

7 tiles

Explanation:

There are 100 centimeters in a meter. This means the area of the floor in centimeters is:

30.24 × 100 = 3024

Now that the measures are in the same unit, we can divide the area of the floor by the area of the tiles to determine how many you would need:

3024 ÷ 432 = 7

You'll need exactly 7 tiles to fill the space.
