Perimeter = 6cm + 6cm + 9cm + 9cm = 30cm
54
It is 3 inches
7cm x 9cm= 63 sq.cms
add 9cm to10cm and you come up with 19cm is ths correct?
90 mm
90mm is 9cm
9cm = 90mm
there are 10mm in a cm, so 88mm is closer to 9cm because it is 8.8cm
9cm
times it by ten.. 90mm
10mm = 1cm so 90mm = 9cm
90mm divided by 10 = 9cm
900 mm Algebraic Steps / Dimensional Analysis Formula 90 cm*10 mm 1 cm=900 mm
10 millimeters are in 9 centimeters
it is less than because 1cm. = 10mm. so 9cm. is 90mm. and then you add the 9mm. to that 90mm.
