Well, first, both the length and width must be in either meters or centimeters. We cannot multiply meters and centimeters together and get a useful result. We know that 1 meter is 100 cm and 1 cm is 1/100 meter. We also know that A=L*W, soooo:
We'll work with meters first
A=(1 meter)*(34/100 meter)=34/100 square meters (Remember meter*meter=square meter or meter^2)
Now let's deal in cm
A=(100 cm)*(34 cm)=3400 square centimeters
Now the question is:
Does 34/100 sq meters=3400 square centimeters??
Well, 1 square meter=(100 cm)*(100 cm)=10,000 square cm
So 34/100 square meters=(34/100)*(10,000) square cm and that equals 3400 square centimeters.
So you could use either meters or centimeters and the answer, of course, would be in square meters or square centimeters
