Algebra.Com's Answer #669259 by addingup(3677)![]() ![]() You can put this solution on YOUR website! The area of a regular polygon is: \n" ); document.write( "area = (1/2)(apothem)(perimeter) \n" ); document.write( "A heptagon has 7 sides, thus: \n" ); document.write( "7sides times 7 inches each side = 7*7 = 49 is the perimeter. Now back to the formula: \n" ); document.write( "(1/2)(3)(49) = (1/2)(137) = 68.5 is the area of your heptagon \n" ); document.write( ": \n" ); document.write( "John \n" ); document.write( " \n" ); document.write( " |
