Question

Eventhough i solved it i don't understand how to fill the colors

Answer 1

If you weren't assigned a specific color for each box, choose a color for the four rectangles. Each answer in the section should be colored with that same color.  It looks like you have that golden yellow for everything in the lower left section.

Answer 2

"color the piece according to your color chart." Do you have that? If you don't, I wouldn't worry, you still did all the work and got all the answers, so your teacher should be fine with it.
