The length of the rectangle is 6 cm and the width is 2 cm less. Find the area and perimeter of the rectangle.

From the condition of the problem, we know that the length of the rectangle, denote it by a, is 6 centimeters, and its width, designated as b, is 2 centimeters less. Thus, we get that the rectangle has the following parameters:

a = 6 cm
b = a-2 = 6-2 = 4 cm

Knowing the length and width of the rectangle, we can find its area and perimeter. To find the area, we can use the following formula:

S = a * b = 6 * 4 = 24 cm square

We can also find the perimeter using the formula:

P = 2 * (a + b) = 2 * (6 + 4) = 2 * 10 = 20 centimeters
