L = 3W-60
\n" ); document.write( "2L + 2W = 960
\n" ); document.write( "Substitute for L:
\n" ); document.write( "2(3W-60)+2W = 960
\n" ); document.write( "Distribute the 2 (Distributive Properties of Multiplication)
\n" ); document.write( "6W-120+2W = 960
\n" ); document.write( "8W = 1080
\n" ); document.write( "W = 135
\n" ); document.write( "and the Length: (135*3)-60 = 345
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
\n" ); document.write( "Check:
\n" ); document.write( "2(135) + 2(345) = 960
\n" ); document.write( "270 + 690 = 960 Correct
