Question

Arbaz plans to tile his kitchen floor with green square tiles. Each side of the tile is 10 cm. His kitchen is 220 cm in length and 180 cm wide. How many tiles will he need?

Answer 1

Length of kitchen = 220 cm
Each side of tile = 10 cm
Number of tiles that can be placed along its length = $\frac{\mathrm{Length}\mathrm{of}\mathrm{kitchen}}{\mathrm{Length}\mathrm{of}\mathrm{each}\mathrm{tile}}$

= $\frac{220}{10}$
= 22

Breadth of kitchen = 180 cm
Length of each side of tile = 10 cm
Number of tiles that can be placed along its breadth = $\frac{\mathrm{Breadth}\mathrm{of}\mathrm{kitchen}}{\mathrm{Breadth}\mathrm{of}\mathrm{each}\mathrm{tile}}$

= $\frac{180}{10}$
= 18

Number of tiles that he will need for kitchen = 22 $\times$ 18
= 396
