Answer 1

✨Answer:

Option ( C) : 21,000

✨Step-by-step explanation :

if length of wall is 20 cm and breadth of wall is 30 cm.

Then ,

Area of wall = length x breadth

Area of wall = 30 x 20 = 600 sq cm.

Now,

For 1 cm^2 no of bricks required = 35.

Then,

No of bricks required for 600 sq cm

= 35 x 600

= 21 000

➡No of bricks required to build the wall is 21 000 bricks.
