Let x= base
\n" ); document.write( "4x= height\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Area = \"%28b%2Ah%29%2F2\"
\n" ); document.write( "Area = \"%28x%2A4x%29%2F2=18\"
\n" ); document.write( "\"2x%5E2=18%7D%7D%0D%0A%7B%7B%7Bx%5E2=9\"
\n" ); document.write( "\"x=3\" inches (NOTE: Reject x=-3!)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Base = x = 3 inches
\n" ); document.write( "Height=4x=12 inches\r
