What is "confuised" and what does the condition of being whatever that is have to do with determining the measurement of a square?

Let represent the measure of the side of the original square. Then is the measure of the side of the enlarged square.

The area of a square is given by squaring the measure of one side. Hence, is a representation of the area of the enlarged square. Also, we are given that is a representation of the area of the enlarged square. So:



Taking the square root of both sides and discarding the negative root because we are seeking a positive measure of length:





And since we set up the problem so that represents the measure of the side of the original square, that is the answer.
