Algebra.Com's Answer #80179 by BrittanyM(80)![]() ![]() ![]() You can put this solution on YOUR website! In order to solve this problem, we must begin with the formula for the perimeter: \n" ); document.write( "P=2L + 2W \n" ); document.write( "Where the legnth is twice the width plus two (L=2W+2) \n" ); document.write( "Since you know that the perimeter is 34, \n" ); document.write( "substitute 34 for P and 2W+2 for L. \n" ); document.write( "34=2(2W+2)+2W \n" ); document.write( "34=4W+4+2w \n" ); document.write( "34=6W+4 \n" ); document.write( "30=6W \n" ); document.write( "w=5 \n" ); document.write( "Now solve the equation for L, substituting 5 for W. \n" ); document.write( "34=2L+2(5) \n" ); document.write( "24=2L \n" ); document.write( "L=12 \n" ); document.write( "So the width is 5 and the legnth is 12. :) \n" ); document.write( " |
