Question

a square wall of side lenght 3.3 m is covered with rectangular tiles of length 22cm and breadth 11cm how many tiles are required to cover entire wall​

Answer 1

Answer:

45 tiles..

Step-by-step explanation:

Side of wall = 3.3 m = 330 cm

Area of wall = 330 × 330 cm² = 108900 cm²

Area of tiles = 22 × 11 cm²

A.T.Q

No. of tiles = 108900/242 = 45

Answer 2

Answer =  450

Step-by-step explanation:

Step 1 of 3

The length of the rectangular tile =22 cm =22100=0.22 m.

And the breadth of the rectangular tile =11 cm =11100=0.11 m.

Step 2 of 3

So. the area of the rectangular tile:

=l×b

=0.22×0.11

=0.0242 m2.

Step 3 of 3

Now, the area of the square wall = side2

=3.32=10.89 m2.

Therefore, the number of the rectangular tiles required to cover the entire wall:

=10.890.0242

=450.
