The area of the rectangle is calculated by the formula:
S = a * b.
Let’s find this value for such a figure, provided that the length is 12 dm, and the width = 6 dm:
S = 12 * 6 = 72 dm².
The opposite sides of a rectangle are equal, so its perimeter is determined by the formula:
P = 2a + 2b = 2 * 12 + 2 * 6 = 24 + 12 = 36 dm.
