You work in a bakery, and you are adding an edible lace border around the top edge of a quarter sheet cake. A quarter sheet cake is rectangular with a length of 13 inches and a width of 9 inches. What is the length of the border around the cake?

The border goes around the cake’s top edge, so find the rectangle’s perimeter: 2 × (length + width). Using 13 inches and 9 inches gives 2 × (13 + 9) = 44 inches. The border is 44 inches long, which is choice D.
