A rectangle is a rectangle with equal opposite sides and right angles.
The perimeter is the sum of all sides. For such a figure, it is determined by the formula:
P = 2a + 2b. Let’s find its value for a rectangle whose length is 13 cm, and the width is 2 cm less (13 – 2 = 11 cm):
P = 2 * 13 + 2 * 11 = 26 + 22 = 48 cm.
