    19. A scale drawing of Corinne’s bedroom floor is shown below. All given dimensions are in feet, and all intersecting line segments shown are perpendicular. Corinne wants to completely cover the floor with square hardwood tiles. Each tile has a side length of 1 foot, and no tiles will be cut. How many tiles will Corinne need to cover the floor?
    The bedroom floor can be seen as being consisting of one rectangle and a square with lengths as below: Thus the area is $$5\times5+6\times9=79$$. The number of tiles needed is $$\frac{79\ ft^2}{1 \ ft^2}=79$$
