==section input Find distance between 2 points with the coordinates: x1 *[input x1=0] y1 *[input y1=0] x2 *[input x2=1] y2 *[input y2=1] You may put negative numbers for negative coordinates. ==section solution perl my $soln = sqrt(($x1-$x2)*($x1-$x2) + ($y1-$y2)*($y1-$y2)); print "The distance (denoted by d) between two points in two dimensions is given by the following formula: {{{d=sqrt((x1-x2)^2 + (y1-y2)^2)}}} Thus in our case, the required distance is {{{d=sqrt(($x1-$x2)^2 + ($y1-$y2)^2)= $soln }}} For more on this concept, refer to <A HREF=Distance_formula.wikipedia>Distance formula</A>. "; ==section output soln, ==section check x1=0 y1=0 x2=3 y2=4 soln=5
