Question

find the distance between the points a (9,3) and b (15,11)

Answer 1

$\huge{\pink{\underline{Solution}}}$

A (9,3)

B (15,11)

$AB = \sqrt{ (x_2-x_1)^{2} + (y_2-y_1)^{2}} \\\\ AB= \sqrt{ (15-9)^{2} + ( 11-3)^{2}}\\\\ AB = \sqrt{ (6)^{2} +(8)^{2} } \\\\ AB = \sqrt{ 36 +64}\\\\ AB =\sqrt{ 100} \\\\ AB = 10 unit$
