Thank you for the opportunity to help you with your question!

Hi ! this is an odd question. Maybe you are just supposed to add up the shapes? So 2 squares + 3 squares = 5 squares in all. Then also 1 circle + 3 circles = 4 circles in all.

Please let me know if you need any clarification. I'm always happy to answer your questions.

I think the triangles are just put there for background. Similar as when in word problems in math you are always given extra unneeded information. In that type of problem half the challenge is to rule out unnecessary information. So glad I helped you!
