The area of a rectangle whose opposite sides are equal corresponds to the formula:

S = a * b.

Let’s find this value, provided that one side is 2 cm, and the other is 4 times larger:

S = 2 * (2 * 4) = 2 * 8 = 16 cm².

The perimeter is calculated using the formula:

P = 2a + 2b = 2 * 2 + 2 * 8 = 4 + 16 = 20 cm.
