Tony has a piece of quilt that is 6 feet by 24 feet. If he wants to turn it into a square and use all the fabric, how long is each side of the square? Give me reasons, before answering the question

The quilt is 144 square feet because 6 x 24 = 144. A square quilt would be 12 feet per side because √(144) = 12. So the final answer is 12.
