let x = length of the sides of the equilateral triangle
\n" ); document.write( "so, the length of rectangle is x also and the width is x - 2\r
\n" ); document.write( "\n" ); document.write( "Perimeter of the triangle = Perimeter of the rectangle - 4
\n" ); document.write( " $\"3x=2%28x%2Bx-2%29-4\"$
\n" ); document.write( " $\"3x=%284x-4%29-4\"$
\n" ); document.write( " $\"4x-3x=4%2B4\"$
\n" ); document.write( " $\"x=8\"$
\n" ); document.write( "
\n" ); document.write( "length of rectangle = 8 inches
\n" ); document.write( "width of rectangle = x - 2 = 8 - 2 = 6 inches \n" ); document.write( "

\n" );
