alright I may be wrong but...
from the size of this image I measured (ruler on monitor, dont worry it is a flat screen)
The pen in that image is about
3.8125 inches long
Half the length of the top $20 is about
2.5 inches making the full length about
5 inches in that image
Assuming that pen is the length of a regular pen (about
5.25 inches based on the pen I measured)
I figure the Length (<--->) of the money is about
6.9 inches
now half the width (|) of that money on the image is about
1.5 inches making it about
3 inches (on the image)
that would make the area of that money (in the image) about
15 inches squared
So the width (|) of the money (in real life) should be about
4.14 inches
so the area of the money should be about
28.6 inches squared
Now Im going to stress that my math could be wayyy off but its the best i have to determine the size for you guys.
also I got my measurements from an image on my screen, other image measurements could vary. also It is rough because i couldnt get an exact measurement for the pen to compare.
I will feel really dumb if it is wrong lol but yea.
