Question

a room has length 5 metre and breadth 4 metre its floor is to be covered with square tiles each of side 20 cm find the number of tiles needed to cover the floor​

Answer 1

To be precise, in theory*, you’ll need 300 tiles of 20 x 20 cm.

Well each metre would require five 20 x 20 cm tiles laid side-by-side.

So for the length of 4m, you would need 20 (4 x 5) tiles across and for the breadth of 3 m, you would need 15 (3 x 5) tiles across.

So in total you would need 20 x 15 = 300 tiles to cover the floor.
