The length of a rectangle is 7 meters longer than its width. What is the width of this rectangle if its perimeter is equal to 86 meters?\r
\n" ); document.write( "\n" ); document.write( "width =w
\n" ); document.write( "length = w+7\r
\n" ); document.write( "\n" ); document.write( "perimeter = 2(L+W)
\n" ); document.write( "perimeter = 2(w+w+7)=86\r
\n" ); document.write( "\n" ); document.write( "2(2w+7)=86
\n" ); document.write( "/2
\n" ); document.write( "2w+7=43
\n" ); document.write( "2w=43-7
\n" ); document.write( "2w=36
\n" ); document.write( "/2
