Laser Daggerboard Size and dimensions?

I live in Utah, and I'm 13 years old. There isn't a ton of sailing here, and I'm doing a math project on laser sailing, I need to figure out the area in either square inches, feet, or cm of the daggerboard, but only the part that is in the water at all times. Does anyone know this off the top of their head. I sadly don't have access to a laser, or I would measure it myself. Thanks

341 mm x 680 mm = about 2320 square centimetres = just a bit less than one quarter of a square metre.

Thank you so much, this information has come in so handy to me as I work on my project!

A rope handle passing through not more than two holes of maximum diameter 12.5 mm above a line drawn from the bottom of the centreboard stop, parallel to the top of the centreboard is permitted. A plastic/rubber tube and/or tape are permitted on the handle of the centreboard.
