The perimeter of any rectangle can be calculated using the formula:

P = 2 * (a + b), where P is the perimeter of the rectangle (P = 64 decimetres), a is the length of the first side (a = 14 decimeters), b is the length of the second side.

Let us express and calculate from the formula the length of the second side of the rectangle:

64 = 2 * (14 + b).

64/2 = 14 + b.

32 = 14 + b.

b = 32 – 14.

b = 18 decimetres.

Answer: The length of the second side of the rectangle is 18 decimeters.
