what hapens to the perimeter of a rectangle if we multiply both its length and widht by 2? by 3? by 10? by n? I really don't know where to start here.
\n" ); document.write( "---
\n" ); document.write( "Start with the formula:
\n" ); document.write( "P = 2(L+W)
\n" ); document.write( "---
\n" ); document.write( "P/2 = (L+W)
\n" ); document.write( "====
\n" ); document.write( "Now double length and width:
\n" ); document.write( "Multiply both sides by 2 to get:
\n" ); document.write( "P = (2L+2W) ; The perimeter doubled
\n" ); document.write( "---
\n" ); document.write( "Multiply both sides by 3 to get:
\n" ); document.write( "3(P/2) = 3L + 3W : The perimeter is multiplied by 3
\n" ); document.write( "etc.
