Solution:\r
\n" ); document.write( "\n" ); document.write( "Let the side of the square be “x”.
\n" ); document.write( "The perimeter of the square = 4x
\n" ); document.write( "Since the side of a equilateral triangle is 6 inches shorter than the side of a square,
\n" ); document.write( "We can write it as,
\n" ); document.write( "The side of the equilateral triangle is x - 6
\n" ); document.write( "The perimeter of the triangle = (x - 6) + (x - 6) + (x - 6)
\n" ); document.write( " = 3(x - 6)
\n" ); document.write( "Given that the perimeter of the square is 36inches more than perimeter of the triangle.\r
\n" ); document.write( "\n" ); document.write( "The perimeter of the square = 36 + 3 (x -6)
\n" ); document.write( " 4x = 36 - 18 + 3x
\n" ); document.write( " 4x = 18 – 3x
\n" ); document.write( " 4x -3x = 18
\n" ); document.write( " x = 18
\n" ); document.write( " x = 18 inch\r
\n" ); document.write( "\n" ); document.write( "The length of the side of the square = 18inch
\n" ); document.write( "
\n" ); document.write( "
\n" );
