The rectangle is 31 inches long and 19 inches wide. find its perimeter and area?

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.
