In order to find the perimeter of a rectangle, you simply need to add up the lengths of all four sides. The formula for finding the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.To find the perimeter of a rectangle with a length of 5 cm and a width of 3 cm, you can substitute these values into the formula:P = 2(5) + 2(3)P = 10 + 6P = 16 cmTherefore, the perimeter of the rectangle is 16 cm.
