O.K at the beginning of the problem it says 3 by 5 so you multiply 3 times 5 do you follow?

anonymous · Answer

correct answer is actually 16ft...so sorry...Yes I follow so far

anonymous · Answer

thats is O.K
1 foot = 30.48 OR 30 12/25 cm
1 cm = 0.1 OR 1/10 Decimeters
These are the Conversions from feet to cenimeters and cenimeters to decenimeters. this is how you are gonna finnd dout how to get your answer

okay so I understand how we got 16 feet. Now please give me simple instructions on how to conver to centimeters and decimeters.  Thanks

radar · Answer

Take the number of centimeters    example 12 cm.  to convert that to decimeter you multiply by .1  Now 12 cm would become 1.2 dm
