| Formula for the area of a rectangle: S = a * b; where a is the length of the rectangle, b is the width of the rectangle.

1. Find the second side of the rectangle, from the condition we know that the width is 3/5 of the length, we get:

a = 3/5 * b => b = 6 cm / (3/5) = 10 cm;

2. Now we find the area of the rectangle, and the area formula is S = a * b; where a is the length of the rectangle, b is the width of the rectangle, we get:

S = a * b = 6 cm * 10 cm = 60 cm ^ 2;

Answer: the area of the rectangle = 60 cm ^ 2.
