​Kishore plans to tile his kitchen floor with square tiles. Each side of the tile is 10 cm. The kitchen is 2.4 m long and 1.6 m wide. How many tiles will Kishore need? ​

Correct option is C

Given: 

Dimension of kitchen = 2.4 m $$\times$$ 1.6 m

Dimension of square tile = 10 cm 

Formula Used: ​

Area of rectangle = length $$\times$$ breadth

Area of square = (side)² 

Solution: ​

length of the side in meter = $$\frac{1}{10}m$$ 

Number of tile = $$\frac{2.4 \times 1.6}{\frac{1}{10} \times \frac{1}{10}}$$ 

= $$2.4 \times 1.6 \times 10 \times 10$$ 

= 384
