The length of a residential bathroom is 3 feet longer than the width. In order to make the bathroom handicapped accessible the length of the bathroom is increased by 3 feet, and the width is increased by 2 feet. The area of the handicapped accessible bathroom is 37 ft.² larger than the area of the residential bathroom. Find the dimensions of the residential bathroom and the handicapped-accessible bathroom.

The Pythagorean Theorem is helpful for two-dimensional navigation.   You can use it along with two lengths to calculate the shortest path. The lengths north and west will be the triangle's two wings, and the diagonal will be the shortest line separating them.  The same principles can be used for air navigation. He is best known in the modern day for the Pythagorean Theorem, a mathematical formula which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares on the other two sides.
