\n" ); document.write( "one side =1134.4, Square of side 1286863.36,(A)
\n" ); document.write( "Other 5.56, Square of side 30.9136 (B)
\n" ); document.write( "difference of squares = (A-B)1286832.446
\n" ); document.write( "So third side =square root of 1286832.446 = 1134.386374\r
\n" ); document.write( "\n" ); document.write( "Area = 1/2*b*h = 0.5*5.56*1134.386374= 3153.59412 sq units\r
\n" ); document.write( "\n" ); document.write( "OK.
