Hi dear,
\n" ); document.write( "The lenght of AB is given by
\n" ); document.write( "\"AB=sqrt%28%28x%5B2%5D%5E2-x%5B1%5D%5E2%29%2B%28y%5B2%5D%5E2-y%5B1%5D%5E2%29%29\"
\n" ); document.write( "From your question,
\n" ); document.write( "x2=7
\n" ); document.write( "x1=3
\n" ); document.write( "y2=9
\n" ); document.write( "y1=1
\n" ); document.write( "put the above in the formula,and get the lenght of
\n" ); document.write( "AB as 8.9
\n" ); document.write( "Hope this helps?
