Problem 3

Tyler’s rectangular room has a total perimeter of 54 feet. The length of Tyler’s room is 13 feet. What is the width of the room? Explain or show your reasoning.

Show Solution

Solution

14 feet. Sample response: $13 + 13 = 26$ so I know that two sides take up 26 feet. $54 -26 = 28$ so the other two sides are 28 feet. I can divide by 2 to get their length $28 \div 2 = 14$ .
