Repairing a hull

In the latest storm and flooding, my sunfish got damaged. Photos are attached, and I can provide more information. I was wondering if anyone could possibly point me to how to start to repair it (or if it is possible?). I am very new to these things and would love to try to make it sailable (doesnt have to be beautiful) and try to get my daughter back on the water in it this summer.
Thank you so much in advance!
