This rectangle has been cut up into squares of varying sizes. Both small squares have side length 1 unit. The square in the middle
has side length x units.
1. Suppose that x is 3. Find the area of each square in the diagram. Then find the area of the large rectangle.
2. Find the side lengths of the large rectangle assuming that x is 3. Find the area of the large rectangle by multiplying the length
times the width. Check that this is the same area you found before.

3. Now suppose that we do not know the value of x. Write an expression for the side lengths of the large rectangle that
involves x.
