Algebra.Com's Answer #616922 by addingup(3677)![]() ![]() You can put this solution on YOUR website! L= W+10 Let's use this value for Length in the formula below: \n" ); document.write( "2L+2W= perimeter \n" ); document.write( "2(W+10)+2W= 220 Multiply: \n" ); document.write( "2W+20+2W= 220 Subtract 20 on both sides and add W on left: \n" ); document.write( "4W= 200 Divide both sides by 4: \n" ); document.write( "W= 50 This is the width, and the length is 10 more: \n" ); document.write( "L= 50+10= 60 \n" ); document.write( "Proof: \n" ); document.write( "2(50)+2(60)= 220 \n" ); document.write( "100+ 120= 220 \n" ); document.write( "220 = 220 We have the correct answer \n" ); document.write( " \n" ); document.write( " |
