Question

A rectangular bathroom floor is covered with square tiles that are 1 1/2 feet by 1 1/2 feet. The length of the bathroom floor is 10 1/2 feet and the width is 6 1/2 feet

Answer 1

The number of square tiles required to cover the bathroom floor is approximately 31.

Explanation:

The dimensions of the rectangular floor of the bathroom are:

Length = 10.5 ft.

Breadth = 6.5 ft.

The dimensions of the square tiles are:

Side = 1.5 ft.

The area of the rectangular floor of the bathroom is:

`Area\ of Bathroom\ floor=Length* Breadth\\=10.5*6.5\\=68.25`

The area of 1 square tile:

`Area\ of\ 1\ square\ tile=(SIde)^(2)\\=(1.5)^(2)\\=2.25`

The number of tiles required to cover the bathroom floor is:

`Number\ of\ tiles=(Area\ of\ bathroom\ floor)/(Area\ of\ 1\ square\ tile) \\=(68.25)/(2.25)\\ =30.3333\\\approx31`

Thus, the number of square tiles required to cover the bathroom floor is approximately 31.
