You can put this solution on YOUR website!
Perimeter(P) of a rectangle = 2l + 2w, where l is the rectangle's length and w is the width
\n" ); document.write( ":
\n" ); document.write( "we are given l = 2x and w = x, then
\n" ); document.write( ":
\n" ); document.write( "P = 2(2x) + 2x = 6x
\n" ); document.write( ":
