<u>The Perimeter of a Rectangle</u>
Given a rectangle of width W and height H, the perimeter is calculated as:
P = 2(W + L)
Jon used 56 cm of ribbon to go around the edge of a rectangular lid. This means the perimeter is:
2(W + L) = 56
Dividing by 2:
W + L = 28
Since the lid was L=13 cm long, the width is:
W = 28 - 13 = 15
The width of the lid is 15 cm
