Question

A room is 5.4 m long and 4.2 m wide. It
takes 1575 square tiles to cover the floor.
Calculate the area of each tile and work out
its dimensions.​

Answer 1

Area of the room = 5.4m × 4.2 m

Thus area = 22.6 ${m}^{2}$

Number of square tiles = 1575

Thus The area of each tile:

$= \dfrac{22.6}{1575} {m}^{2}$

$\bold{\red{= 0.0144 {m}^{2}}}$

Now the dimensions of square tile will be:

$= \sqrt{0.0144} m$

$\bold{\red{= 0.12m}}$
