Question

The floor of a room measures $4.5$ metres $\times 3$ metres. Find the minimum number of complete square marble slabs of equal size required to cover the entire floor.

Answer 1

Area $=4.5\times 3$ $m^2$

Let side of square be $x$

Area of square = $x^2$

$\frac{4.5\times 3}{x^2}=I$($I$ is an integer)

$\therefore whenI=6$

$x^2=2.25$

$x=1.5m$
