\displaystyle\huge\red{\underline{\underline{Solution}}}

FORMULA TO BE IMPLEMENTED

The distance between two points

 ( x_1, y_1)  \:  \: and  \:  \: ( x_2, y_2 )is

 \sqrt{ {( x_1 -  x_2)}^{2}  + { ( y_1 -  y_2 )}^{2} } \:  \:  \:  \:  \:  \: unit

GIVEN

Two points (a,b) , (-a,-b) are given

TO DETERMINE

The distance between the above two points

EVALUATION

The distance between the points (a,b) , (-a,-b) is

 =  \sqrt{ {(a + a)}^{2}  + {(b + b)}^{2} }  \:  \:  \:  \: unit

 =  \sqrt{ {(2a )}^{2}  + {(2b)}^{2} }  \:  \:  \:  \: unit

 =  \sqrt{ {4a }^{2}  + {4b}^{2} }  \:  \:  \:  \: unit

 =  \sqrt{ 4({a }^{2}  + {b}^{2}) }  \:  \:  \:  \: unit

 = 2 \sqrt{ ({a }^{2}  + {b}^{2}) }  \:  \:  \:  \: unit
