PCR

I am asked to work out the size of the product of a PCR reaction, I am not sure how to do this and I would appreciate any help- if its quite a long process, then I would appreciate any guidelines on how to do this.
 
I have two primers- a forward (ACTCTCACTGCTAAGGACA) and reverse (TGGCCATGACCACAAGGATG), which are designed to amplify a section of a cloned gene. If a PCR reaction is ran, what is the expected size of the product in base-pairs, if the DNA sequence is: TACACACAACATGTCCA
CTCTCACTGCTAAGGACACGGAAACAGTC AAGGCCTTCTGGGCCAAAGTGGCTGGAAA GC

The above DNA sequence was derived from an RNA sample, and reverse transcribed to make a cDNA clone and then subjected to the PCR.

Also if this cDNA had not been reverse transcribed, and it was subjected to gel electrophoresis, and had the same band pattern as an RNA sample that had been reverse transcribed, then what conclusions might be reached?

Thank you very much
