Question
Raj is living in a big room. The dimension of the room is 15.6 m x 19.5 m. He wants to cover the floor with the tiles, each of them measuring 120 cm x 150 cm. Find the exact number of tiles required by Raj to cover the floor.
Answer: Option A
:
A
First of all, we have to convert all the dimensions into the same unit. ( 1 m = 100 cm )
The number of tiles × Area of each tile = Area of the entire room.
⇒ Number of tiles = 15.6×19.51.2×1.5 = 169tiles.
