Let x = measure of the diagonal\r
\n" ); document.write( "\n" ); document.write( "By Pythagorean Theorem,
\n" ); document.write( "x^2 = (9sqrt(3))^ 2 + (9sqrt(3))^2
\n" ); document.write( "x^2 = (81*3) + (81*3)
\n" ); document.write( " = 243 +243
\n" ); document.write( " = 486
\n" ); document.write( "x = sqrt(486)
\n" ); document.write( " = sqrt(81*6)
\n" ); document.write( " = 9 sqrt(6) inches is the measure of the diagonal of the square
\n" ); document.write( "
