Multiply 6-10 Groups in Perimeter Problems Part I 3-50
Reinforce multiplication facts by finding the perimeter of regular hexagons, heptagons, octagons, and nonagons. If a hexagon's sides all measure 9 inches, what's its perimeter? Since the total length of 6 sides is 6x9 = 3x9 + 3x9 = 27+27 = 54, the perimeter is 54 inches. Find and add partial lengths to get the total length.
