Question

7. A marble tile measures 25 cm by 20 cm. How many tiles will be required to cover the wall of size
400 cm by 300 cm.​

Answer 1

Answer:

Ok I will tell you the answer

Step-by-step explanation:

Length of marble tile = 25 cm

Breadth of marble tile = 20 cm

Area = 25 x 20 = 500 cm2

Length of wall = 400 cm

Breadth of wall = 300 cm

Area = 400 x 300 = 120000 cm2

No. of marble tiles required to cover the wall = 120000/500

First cut the zero from 120000 and 500

means 1200/5 = 240 marble tiles
