Algebra.Com's Answer #189314 by palanisamy(496)![]() ![]() ![]() You can put this solution on YOUR website! Let the width of the rectangle = x \n" ); document.write( "Given, the length is 2 m more than twice the width. \n" ); document.write( "So the length = 2x+2 \n" ); document.write( "Perimeter is 2(2x+2+x) = 142 \n" ); document.write( " (3x+2) = 142/2 \n" ); document.write( " 3x+2 = 71 \n" ); document.write( " 3x = 71-2 \n" ); document.write( " 3x = 69 \n" ); document.write( " x = 69/3 \n" ); document.write( " x = 23m \n" ); document.write( "Therefore width = 23 m \n" ); document.write( " length= 2x+2 = 2*23+2 = 48m \n" ); document.write( " |
