Question

Find the distance between the points ( a + b, a - b) and (a - b, -a – b)​

Answer 1

Step-by-step explanation:

Let x1 = a + b

x2 = a - b

y1 = a - b

y2 = -a -b

By applying Distance Formula,

$\sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} }$

By substituting the values,

$\sqrt{ {((a + b) - (a - b))}^{2} + {((a - b) - ( - a - b))}^{2} }$

$\sqrt{ {(a + b - a + b)}^{2} + {(a - b + a + b)}^{2} }$

$\sqrt{ {(2b)}^{2} + {(2a)}^{2} } \\ \\ = > 2a + 2b = 2(a + b) \: units$
