Answer:
To make a square from a rectangle, we need to cut off a piece from either the length or the width of the rectangle. In this case, we can cut a square piece with a length of 5cm from the longer side of the rectangle, leaving us with a smaller rectangle with dimensions 5cm by 1cm.
To make a square from this smaller rectangle, we need to cut off a piece from the width of the rectangle. We can cut a square piece with a length of 1cm from the shorter side of the rectangle, leaving us with a square with a side length of 1cm.
Therefore, the area of the square is 1cm x 1cm = 1 square cm.
