Answer 1

Answer:

$6.7\ units$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

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

we have

(4,2) and (7,8)

substitute the values in the formula

$d=\sqrt{(8-2)^{2}+(7-4)^{2}}$

$d=\sqrt{(6)^{2}+(3)^{2}}$

$d=\sqrt{45}\ units$

$d=6.7\ units$
