Answer 1

Step-by-step explanation:

Given :-

• 4 meter by 3 meter size walls.
• 25cm and 20cm to cover

To Find :-

• How much marble tiles will be needed?

Solution :-

Rectangle marble tile area = 25×20=500m =5 cm

No. of tile = area of the wall cover/ marble tile area

Cover of wall area = 4m × 3m = 12m^2

Hence 240 marble will be needed.
