Question

A tile is 15cm long and 10 cm wide.the four walls of the kitchen to be tiled. If the length and breadth of each wall is 440 cm and 750 cm, how many tiles required to tile entire kitchen?

Answer 1

Area of $4$ walls = $4(440\times 750)=1320000$ $c{m}^2$

Area of $1$ tile = $15\times 10=150$ $c{m}^2$

Therefore,

Number of tiles required = $\frac{1320000}{150}=8800$ $tiles$
