7.EE.2 7.EE.1 7.EE.1 7.EE.1 7.EE.1 16. A. 2(15) + 2(𝑤 + 5); 2(15 + 𝑤 + 5) B. Sample Answer: In order to find the expression, I had to use several pieces of information given to me in the problem. I am first told that Casey and her mom want to build a rectangular garden so I know that the perimeter of this shape can be found using the formula of the perimeter 2𝑙 + 2𝑤 or 2(𝑙 + 𝑤). Based on the information in the problem I know that the length is 15ft and the width is equal to 𝑤 + 5). I then plugged these values for length and width into the formulas for perimeter and found my two expressions, 2(15) + 2(𝑤 + 5) and 2(15 + 𝑤 + 5). C. 72 feet
