Question

5. The length and breadth of a room are 15 feet x 12 feet. The floor of the room has to be laid with tiles of
dimensions 1 feet x — feet. If one box contains 40 tiles, how many such boxes of tiles will be required to
pave the floor of the room?
​

Answer 1

Step-by-step explanation:

Breadth = 12 feet

Length = 15 feet

Hoping that the tile side is equal to 1 feet and is a square

The area of the floor = 15×12 = 180 feet²

Area of 1 tile = s×s = 1×1 = 1 feet²

Area of 40 tiles = 1 feet²× 40 = 40 feet²

Boxes required to pave the floor = 180/40 = 4.5 boxes
