The length of one side of the rectangle is 3.2 cm and the perimeter is 33.2 cm.

The length of one side of the rectangle is 3.2 cm and the perimeter is 33.2 cm. Find the length of the second side of the rectangle.

To find the perimeter of a rectangle, fold the 4 sides of the rectangle.

P = a + b + a + b = 2 * a + 2 * b.

a = 3.2.

P = 33.2 cm.

Find the width of the rectangle:

33.2 cm = 2 * 3.2 cm + 2 * b;

33.2 cm = 6.4 cm + 2 * b;

26.8 cm = 2b;

b = 13.4 cm.

Answer: 13.4.
