The width of the rectangle is 102 cm, which is 17/18 of its length. Find the perimeter and area of the rectangle.

1) Determine what the length of the rectangle is equal to: 102: 17/18 = 102 18: 17 = 108 (cm);

2) Calculate the perimeter of this rectangle using the formula: P = (a + b) 2 = (102 + 108) 2 = 420 (cm);

3) Find the area of a rectangle by the formula: S = a · b = 102 · 108 = 11016 (cm²).

Answer: the perimeter of the rectangle is 420 cm, and its area is 11016 cm².
