Answer 2

Answer:

20000 bricks.

Step-by-step explanation: First convert meter to centimeter, because if both parameters don't match, you cannot divide them.

So, 25 m becomes 25*100=2500 cm and 16 m becomes 16*100=1600 cm.

Then,multiply 2500 cm and 1600 cm, we get 2500*1600=4000000 cm.

Then,multiply 20 cm and 10 cm we get 20*10=200 cm.

Now, simply divide 4000000 cm by 200 cm, we get 4000000/200=20000.

So, number of the bricks will be 20000.
