How do I place multiple objects in a given area?

I am making a game where you place cards on a board. Is there a way to select an area and have the cards placed to fill up that area? (example: I select a 5x3 area, the cards are 1x1, I placed 15 1x1 cards in the area)

Probably, i'm guessing no one responded because there isn't enough information here, we cannot visualize the game that you can see. If you share how the game looks and how you select an area then we can offer more assistance.
