let hypotenuse be x
\n" ); document.write( "side 1 = x-7
\n" ); document.write( "side 2 = x-14
\n" ); document.write( "..
\n" ); document.write( "x+x-7+x-14=84
\n" ); document.write( "3x-21=84
\n" ); document.write( "add 21
\n" ); document.write( "3x-21+21=84+21
\n" ); document.write( "3x=105
\n" ); document.write( "divide by 3
\n" ); document.write( "x= 35
\n" ); document.write( "..
\n" ); document.write( "base = 35-7= 28
\n" ); document.write( "height = 35-14= 21
\n" ); document.write( "..
\n" ); document.write( "Area = 1/2 * 21*28
\n" ); document.write( "=21*14
\n" ); document.write( "=294 sq. inches
\n" ); document.write( "
\n" );
