The cafeteria uses rectangular trays with a raised edge around them. The area of the flat surface of each tray is 228 Inches squared 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. 6 inches 12 inches 31 inches 62 inches

Answer:

D. 62 inches

Explanation:

Given

Area of each tray = 228 inĀ²

length of the tray = 19in

Required

Perimeter of the tray

First we need to get the width of the tray

Using the formula for calculating area;

A = LW

228 = 19W

W = 228/19

W = 12in

The width is 12in

Next is to get the perimeter of the tray using the formula;

P = 2(L+W)

L is the length

W is the width

P = 2(19+12)

P = 2(31)

P = 62in

Hence the perimeter of the tray is 62inches
