Calculate the perimeter and area of a rectangle if the length of one of its sides is 10 cm 8 mm and the length of the other is 6 times less.

To begin with, let’s translate the length of the rectangle into one measuring unit, 10 cm 8 mm we translate into millimeters = 88 millimeters. Next, we calculate the other side of the rectangle: 1) 88: 6 = 88/6 = 14 4/6 millimeters. Now we can find the perimeter of the rectangle using the formula: P = 2 (a + b). 2) P = 2 (88 + 14 4/6). P = 2 * 102 4/6. (for multiplying by a mixed fraction, we translate it into an incorrect one, 102 4/6 = 616/6) Р = 2 * 616/6. P = 616 * 2/6. P = 1232/6. (we simplify the fraction by reducing it by 2) Р = 616/3. (select an integer) P = 205 1/3.
Answer: P = 205 1/3 millimeters.
