\n" ); document.write( "The perimeter of each triangle is,
\n" ); document.write( "\"Pt=s%2B2d\"
\n" ); document.write( "The total for 4 triangles would be,
\n" ); document.write( "\"P=4s%2B8d\"
\n" ); document.write( "\"d\" is related to the diagonal of the square,
\n" ); document.write( "\"D=d%2Bd=2d\"
\n" ); document.write( "\"D%5E2=s%5E2%2Bs%5E2=2s%5E2\"
\n" ); document.write( "\"D=sqrt%282%29%2As\"
\n" ); document.write( "Substituting,
\n" ); document.write( "\"P=4s%2B8d\"
\n" ); document.write( "\"P=4s%2B4D\"
\n" ); document.write( "\"P=4%28s%2Bsqrt%282%29s%29\"
\n" ); document.write( "\"highlight%28P=4s%281%2Bsqrt%282%29%29%29\"
\n" ); document.write( "
\n" );
