10.1 Area and Perimeter of Rectangles
Here you’ll learn how to find the area and perimeter of rectangles and squares.
What if Ed’s parents were getting him a new bed, and he had to decide what size bed is best for him? Initially he
decided that he would like a king bed. Upon further research, Ed discovered there are two types of king beds, an
Eastern (or standard) King and a California King. The Eastern King has 76′′× 80 ′′dimensions, while the California
King is 72′′× 84 ′′(both dimensions arewidth×length). Which bed has a larger area to lie on? Which one has a
larger perimeter? If Ed is 6’4”, which bed makes more sense for him to buy? After completing this Concept, you’ll
be able to use your knowledge of rectangles to answer these questions.
