dangina [55]

Answer:

19,200 cm^2.

Step-by-step explanation:

The area = 1.2 * 1.6 = 1.92 m^2.

There are 100 cm to 1 meter,  so 1 square meter = 100^2 = 10,000 cm^2.

Therefore 1.92 m^2 = 10,000 * 1.92 =  19,200 cm^2.

MA_775_DIABLO [31]

Step-by-step explanation:

10 \times 30 = 300

which would be 300 hours in 1 month

now if one month is 31 days you would simply multiply 10 by 31.

10 \times 31 = 310

which would be 310 hours
