Algebra.Com's Answer #54341 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! The perimeter of a rectangle is the width+length+width+length. Since the 2 width's are the same we can say w+w=2w. The same thing applies for the length: L+L=2L. So the perimeter formula can be written as:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "So the length is 4 feet \n" ); document.write( "
