The length of the rectangle is 3 2 \ 3 cm, and the width is 1 3 \ 10 cm less than the length. Find the perimeter of the rectangle.

Find the width of the rectangle:

3 2/3 – 1 3/10 = (3 * 3 + 2) / 3 – (1 * 10 + 3) / 10 = 11/3 – 13/10 = 110/30 – 39/30 = (110 – 39 ) / 30 = 71/30 (cm);

Let’s calculate its perimeter (the sum of all sides):

2 * 3 2/3 + 2 * 71/30 = 2 * 11/3 + 142/30 = 220/30 + 142/30 = (220 + 142) / 30 = 362/30 = 12 2/30 cm.

Answer: 12 whole 2/30 cm.
