Let the width of the rectangle be “x” cm, then the length of the rectangle is “5x” cm. Since the perimeter of the rectangle is 1212 cm, the perimeter is found by the formula P = 2 * (a + b), substitute the values into the formula: 2 * (5x + x) = 1212; 2 * 6x = 1212; 12x = 1212; x = 1212: 12; x = 101. So the width of the rectangle is 101 cm, then the length of the rectangle is 5 * 101 = 505 cm.
Answer: 101 cm and 505 cm.
