Jamin wants to paint a wall in his bedroom. In order to know how much paint to buy, he first needs to know the approximate area. There is a window in the middle of the wall, so he'll only need to paint the shaded part shown. How many square feet is just the window? [Note: The wall and window are both rectangular.]

Given:Length of the wall = 8 ftWidth of the wall = 6 ftLength of the window = 2 ftWidth of the window = 18 inTo find:The square feet Jamin planning to paintSolution:Area of the wall = length × width                            = 8 × 6 Area of the wall = 48 ft²Width of the window = 18 inConvert inch to feet.1 feet = 12 inch18 inch = [tex]\frac{18}{12}=1.5[/tex] ftArea of the window = length × width                                  = 2 × 1.5 Area of the window = 3 ft² Area to be painted = Area of the wall - Area of the window                                 = 48 ft² - 3 ft²                                 = 45 ft² Therefore Jamin planning to paint 45 ft².
