Vocabulary Perimeter The OUTSIDE (total) area of a polygon AreaThe INSIDE area of a polygon
Perimeter requires to add all the sides of a polygonFormulas… Perimeter requires to add all the sides of a polygon Perimeter = side + side + side + … OR P = s + s + s +…
to multiply specific sides togetherFormulas… Area requires to multiply specific sides together Area = length x width OR A = l x w Area = side x side A = s² Area = ½ (base x height) A = b x h 2
