One side of the rectangle is 8 2/7 cm, and the other is 3 3/14 cm, less. Find the perimeter of the rectangle.

1. Find the length of the second side of the rectangle. If one side of the rectangle is 8 2/7 cm, and the other is 3 3/14 cm, less than the first:

8 2/7 – 3 3/14 = 58/7 – 45/14 = 58/7 * 14/14 – 45/14 = 58 * 2/14 – 45/14 = 116/14 – 45/14 = 71 / 14 = 5 1/14 cm, second side;

2. Find the perimeter of the rectangle, knowing that this is the sum of the lengths of all sides:

2 * (8 2/7 + 5 1/14) = 2 * (58/7 + 71/14) = 2 * (58/7 * 14/14 + 71/14) = 2 * (116/14 + 71 / 14) = 2 * 187/14 = 187/7 = 26 5/7 cm, perimeter;

Answer: the perimeter of the rectangle is 26 5/7 cm.
