Question

The floor of a room is 5 m 40 cm long and 3 m 20 cm wide. Find the dimensions of the larges square tile that can be fixed on the floor such that no tiles are cut to fix on the floor.​

Answer 1

Answer:

Sides of the floor =5m and 3m

Length=500cm and Breadth300cm [ 1m =100cm]

Area of the floor =lb=500×300=150000cm²

.

Square tile : Side =25cm

∴ Area of a tile =25×25=625cm²

∴ No. of tiles required = Area of the floor ÷ Area of a tile =150000÷625=240.

∴240 square tiles are required to cover the room.

Answer 2

Step-by-step explanation:

Here subtraction is also done in the same way as in the case of numbers. We subtract liters from liters and the difference is calculated in liters. Also when we subtract milliliters from milliliters the difference is calculated in milliliters. It is done in two ways: (i) without regrouping and (ii) with regrouping.
