Algebra.Com's Answer #121145 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! The perimeter of a rectangle is twice the sum of its length/width. The perimeter is 28 meters and length is 2 meters more than twice the width. \n" ); document.write( "What is the length? \n" ); document.write( ": \n" ); document.write( "Let x = the width \n" ); document.write( "then \n" ); document.write( "(2x +2) = length \n" ); document.write( ": \n" ); document.write( "The perimeter equation: \n" ); document.write( "2(2x+2) + 2x = 28 \n" ); document.write( "4x + 4 + 2x = 28 \n" ); document.write( "4x + 2x = 28 - 4 \n" ); document.write( "6x = 24 \n" ); document.write( "x = \n" ); document.write( "x = 4 meters is the width \n" ); document.write( "then \n" ); document.write( "2(4) + 2 = 10 meters is the length \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Check in the perimeter \n" ); document.write( "2(10) + 2(4) = 28 \n" ); document.write( " |
