Question

Length of AB,if A(-3,-7) and B(2,5)
unit
Your answer​

Answer 1

$\underline{\underline{\blue{\bf Answer:-}}}$

$\tt \therefore The \: Distance\: between\: them\:is\:13\:units .$

$\underline{\underline{\orange{\bf Step-by-step\: Explanation:-}}}$

$\underline{\green{\bf Given:-}}$

$\tt:\implies Two\: points \:A(-3,-7)\:and\:B(2,5).$

$\underline{\red{\bf To\:Find:-}}$

$\tt:\implies The \: distance\: between\:them .$

• As we know that ,

$\tt\pink{ :\implies Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}\\\\\tt:\implies Distance =\sqrt{ [ 2-(-3)]^2+[5-(-7)]^2 }\\\\\tt:\implies Distance = \sqrt{ (2+3)^2+(5+7)^2}\\\\\tt:\implies Distance=\sqrt{ 5^2+12^2}\\\\\tt:\implies Distance= {25+144}\\\\\tt:\implies Distance =\sqrt{169}\\\\\underline{\boxed{\red{\tt\longmapsto Distance = 13\:units . }}}$
