| Let’s denote by the unknown variable x centimeters – one side of the rectangle,

Then 15x centimeters is the second side of the rectangle,

Knowing the perimeter, we compose the equation:

2 * (x + 15x) = 19.2;

32x = 19.2;

x = 0.6 centimeters – one side of the rectangle,

0.6 * 15 = 9 centimeters – the second side of the rectangle,

The area of a rectangle is equal to the product of its sides: 0.6 * 9 = 5.4 square centimeters.

Answer: The area of the rectangle is 5.4 square centimeters.
