Question 1 (3 points) 1. Make a shape that has area 25 in2 but that has no (or almost no) straight edges. Explain how you know that your shape has area 253.712. (You do not need to submit the drawing, but definitely explain). Question 3 (3 points) 3. An area problem: The Johnsons are planning to build a 5-foot-wide brick walkway around their rectangular garden, which is 20 feet wide and 30 feet long. What will the area of this walkway be? Before you solve the problem yourself, use Kaitlyn's idea: a. Kaitlyn's idea is to "take away the area of the garden.II Explain how to solve the problem about the area of the walkway by using this idea. Explain clearly how to apply one or both of the moving and additivity principles on area in this case. b. Now solve the problem about the area of the walkway in another way (or not!) than you did in part (a). Explain your reasoning. Question 2 (3 points) 2. The figure shows the floor plan for a one-story house. Calculate the area of the floor of the house, explaining your reasoning. 40ft 32 ft 5. The figure shows the floor plan for a modern, one-story house. Bob calculates the area of the floor of the house this way: 36 x 72 - 18 x 18 = 2268 square feet What might Bob have in mind? Explain why Bob's method is a legitimate way to calculate the floor area of the house, and explain clearly how one or both of the moving and additivity principles on area apply in this case.
