\bf \textit{distance between 2 points}\\ \quad \\ \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) R&({{ 7.7}}\quad ,&{{ 9.9}})\quad % (c,d) S&({{ -5.7}}\quad ,&{{ -4.9}}) \end{array}\qquad % distance value d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2} \\\\\\ RS=√((-5.7-7.7)^2+(-4.9-9.9)^2)\implies RS=√((-13.4)^2+(-14.8)^2) \\\\\\ RS=√(179.56+219.04)\implies RS=√(398.6)\implies RS\approx 19.96496932
