| Since the length and width of the rectangle are known, we find its area and perimeter by the formulas S = a * b, P = 2 * (a + b), where S is the area of a rectangle with length a, width b and perimeter P:
S = 31 * 19 = 589 dm2.
P = 2 * (31 + 19) = 2 * 50 = 100 dm.
Answer: the perimeter of the rectangle is 100 dm2, and its area is 589 dm2.
