How do you covert 126cm long by 118cm wide to square meters?

Answer 1

Two options:

Convert to metres and then calculate area

or

Calculate area and then convert to metres

Option 1:

126 cm * 118 cm = 1.26 m * 1.18 m = 1.26*1.18 sq m = 1.4868 sq m

Option 2:

126 cm * 118 cm = 14868 sq cm = 14868/10000 sq m = 1.4868 sq m

For option 2, you need to remember that 1 m = 100 cm means that 1 sq m = 100*100 = 10000 sq cm.
