A 160cm2 sheet of paper is 8cm wide. What is the perimeter of the sheet?

Decision:
The sheet of paper is rectangular
Rectangle area = length * width
We know the width and area, find the length, for this we divide the area by the width: 160/8 = 20cm
The perimeter of a rectangle is the sum of the lengths of all its sides:
P = (20 + 8) * 2 = 28 * 2 = 56cm
Answer: 56cm
