what is the relationship between cm^2 and mm^2

jimthompson5910 (jim_thompson5910):

Take a square and divide the base and height into 10 pieces. We do this because 10 mm = 1 cm |dw:1428015704366:dw|

TheSmartOne (thesmartone):

Remember that \(\sf 1 cm = 10 mm\)

OpenStudy (anonymous):

D

OpenStudy (perl):

$$ \Large{ 1 cm = 10 mm \\ \therefore \\ (1 cm)^2 = (10~ mm)^2 \\ \therefore \\ 1 cm^2= 10^2~ mm ^2 = 100~ mm^2 } $$

now draw in horizontal and vertical lines for each cut |dw:1428015868598:dw|
