Joaquin has created a small treasure map that is in the shape of a square. He decides to make a larger version of the map, and on this new map, he increases each side by 6 inches. The area of this larger version of the map is 121 square inches.

What are the dimensions of his original, smaller map?

The dimensions of Joaquin's original smaller treasure map are 5 inches for each side. When the sides are increased by 6 inches, the larger map has an area of 121 square inches. This is confirmed by calculating the area of the larger map using its new side length of 11 inches.
