I donât think that formula is right. If you want to double the area (A5 -> A4) you have to use 141% on a photocopier. Thatâs because you increase the length by 141% and the length by 141% 1.41 x 1.41 = 2
1.41 is the square root of 2 Going on that, if you want to increase the area by one third, the final area will be 1.333333 so square root of 1.333333 = 1.54 so you set the photocopier to 154% If you set the photocopier to 200% you double the length and double the width which increase the area four times Brenda > On 1 Oct 2015, at 17:36, [email protected] wrote: > > Thank you Lynne > > That makes sense to me.
