What's a regular heptagon?  "Hept-" means seven, so a "heptagon" is a seven-sided shape.  A "regular" figure's sides are all the same length.  So, each of the 7 sides are the same length.

Remember, perimeter is the sum of the lengths of all the sides in a polygon.  We know one side measures three inches, so each of the others must also measure 3 inches.  3+3+3+3+3+3+3=3*7=21 inches.

Answer: 21 inches
