Problem of the Week - Upper Elementary - Feb. 28, 2021 to March 6, 2021

Upper Elementary:

Question: Adalyn is making sign to carry in a parade. She uses a piece of poster board that is 4 feet long and 3 feet wide and folds it in half, hamburger style. What are the area and perimeter of Adalyn's sign? 

Answer: The area is 6 square feet and the perimeter is 10 feet

Solution: If Adalyn folds the poster board hamburger style, then the new length of the sign will be half of 4 = 2 feet. Since its dimensions are now 2 feet by 3 feet, that means that the area is 2 x 3 = 6 square feet and the perimeter is 2 + 2 + 3 + 3 = 10 feet.
