Question

The square shaped tile has dimensions of 16cm. How many such tiles are required to cover a rectangular shape hall having length 64m and breadth 40m?
​

Answer 1

Length of a rectangular hall L=40 m

Breadth of the rectangular hall B=18 m

So, the area of hall

=L×B=40×18=720 m2

Since,

Length of tiles l=1 m

Breadth of tiles b=50 cm=0.5 m

So, the area of each tile

=l×b=1×0.5=0.5 m2

Therefore, the numbers of tiles are required

=0.5720=1440
