Question

Haru is putting lace around the edge of a rectangular pillow case that has a

length of 12.75 inches and a width of 15.5 inches. How much lace does
he need?

Answer 1

56.5 inches

Explanation:

You want to find the perimeter (or the length around the rectangle) to find much lace he needs. the formula for perimeter is 2L+2W=P. L being length, w being width and p being perimeter. Plug in the values for the equation and get 2(12.75)+2(15.5)=P. Multiply and get 25.5+31=56.5.
