| **The width of the rectangle is 8 decimetres, which is one third of its length. Find the perimeter and area of the rectangle.**

The solution of the problem.

1) Find the length of the rectangle:

8 * 3 = 24 dm.

2) Find the perimeter of the rectangle, that is, the sum of the lengths of all its sides:

P = 8 + 8 + 24 +24 = 16 + 48 = 64 dm.

3) Find the area of the rectangle, that is, the product of its length and width:

S = 8 * 24 = 192 dm ^ 2.

Answer: 64 dm; 192 dm ^ 2.
