Question

The floor of a hall is 16metre 80cm and 15 m 12 cm broad. Fins the least number of square tiles of the same size needed to cover the entire hall. please answer the question!!!! ​

Answer 1

Step-by-step explanation:

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 m

2

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 m

2

Therefore, the numbers of tiles are required

=

0.5

720

=1440
