Question

The length and breadth of a rectangular hall is 30 m and 18 m respectively. How many square tiles of side 3 dcm will be required for flooring the hall?

Answer 1

Answer:

60 tiles are required required for flooring the hall

Step-by-step explanation:

Here given that,

length of a rectangular hall is 30 m

breadth of a rectangular hall is 18 m

Now,

Area of rectangular hall = 30 x 18 = 540 m²

let x tiles are required required for flooring the hall.

x [Area of square] = 540 m²

x [3]² = 540

x = 540/9

x = 60

Hence, 60 square tiles of side 3 m are required required for flooring the hall.
