Algebra.Com's Answer #520687 by lwsshak3(11628)![]() ![]() ![]() You can put this solution on YOUR website! The perimeter of a rectangle is 28cm. The length is 2cm less than three times the width. Determine the length and width. \n" ); document.write( "Now I have tried to solve this and I got \n" ); document.write( "3x-2=length \n" ); document.write( "And let x= width \n" ); document.write( "twice the length plus twice the width=perimeter \n" ); document.write( "2(3x-2)+2x=28 \n" ); document.write( "divide by 2: \n" ); document.write( "3x-2+x=14 \n" ); document.write( "4x=16 \n" ); document.write( "x=4 \n" ); document.write( "3x-2=10 \n" ); document.write( "width=4 cm \n" ); document.write( "length=10 cm \n" ); document.write( " |
