The lengths of the sides of a triangle measured in inches are three consecutive integers. The length of the shortest side is 30% of the perimeter. Find the lengths of the three sides.

*n* = 0.3(*n* + *n* + 1 + *n* + 2)

*n* = 0.3(3*n* + 3)

*n* = 0.9*n* + 0.9

0.1*n* = 0.9

*n* = 9

The sides are 9, 10, and 11 inches; the perimeter is 30 inches.

Check: 30% of 30 is 9.
