| We begin to solve the problem with the condition: find the area and perimeter of a rectangular sheet of paper if its length is 6 dm and width is 3 dm.

To find the area of a rectangle, you need to use the formula S = a * b, and to find the perimeter P = 2a + 2b.

Substitute the known values into the formulas and get: S = 6 * 3.

P = 2 * 6 + 2 * 3.

Let’s perform multiplication, addition and get the desired values:

S = 18 square decimetres.

P = 12 + 6 = 18 decimetres.

Answer: S = 18 square decimeters, P = 18 decimeters.
