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

Answer:

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

Step-by-step 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:

$Area\ of Bathroom\ floor=Length\times Breadth\\=10.5\times6.5\\=68.25$

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:

$Number\ of\ tiles=\frac{Area\ of\ bathroom\ floor}{Area\ of\ 1\ square\ tile} \\=\frac{68.25}{2.25}\\ =30.3333\\\approx31$

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