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 to cover the floor.
First of all, we have to convert all the dimensions into the same unit.
Number of tiles × Area of each tile = Area of the entire room
Number of tiles \(= \frac{15.6 \times 19.5}{1.2 \times 1.5} =\) 169 tiles
