How many tiles whose length and breadth are $12cm$ and $5cm$ respectively will be needed to fit a rectangular region whose length and breadth are respectively
$70cm$ and $36cm$.

Answer 1

Length and Breadth of each rectangular tile are $12cm,5cm$

Area of each tile $=12\times 5=60c{m}^2$

Length and Breadth of rectangular region are $70cm,36cm$
