Area equals length times width. Since the area is x%5E2%2B50x and the width is x, we know that x times something representing the length must equal x%5E2%2B50x.

Notice that if you factor an x out of x%5E2%2B50x, you get:

x%5E2%2B50x=x%28x%2B50%29.

Since x is the width, x%2B50 must be the length.
