1) Since the length of the rectangle is 5 cm, and the width of the rectangle is 2 cm less, then to find the width, you need to subtract 2 cm from the length.
5 cm – 2 cm = 3 cm – the width of the rectangle.
2) In order to find the perimeter of a rectangle, you need to add all the sides or apply the formula S = 2 * (a + b).
P = 5 cm + 5 cm + 3 cm + 3 cm = 2 * 5 cm + 2 * 3 cm = 2 * (5 cm + 3 cm) = 2 * 8 cm = 16 cm.
Answer: the perimeter is 16 cm.
