Question

A rectangular wall is 16 feet wide by 24 feet long. A contractor is looking to tile the wall with square tiles with a side length of 2 feet. If there is no gap left between any of the tiles, how many tiles would the contractor use to completely cover the wall?

Answer 1

96 square tiles are needed

Explanation:

To calculate this, the first thing we need to do is calculate the total area covered by the rectangular wall.

Mathematically, the area of the rectangle = 16 * 24 = 384 ft^2

The next thing we need to do is calculate the area of the square tiles = L^2 = 2^2 = 4 ft^2

the number of square tiles needed = Area of rectangular wall/Area of square tiles = 384/4 = 96
