The cafeteria uses rectangular trays with a raised edge around them. The area of the flat surface of each tray is 228 Inches squ

ared and its length is 19 inches. What is the perimeter of the tray, where the raised edge is?
To find the width, use the formula w = StartFraction A Over l EndFraction, where w represents the width, A represents the area and l represents the length. To determine the perimeter, use the formula P = 2 l + 2 w, where P represents the perimeter, l represents the length, and w represents the width.
