Answer 1

Step-by-step explanation:

The distance between two points is given by formula:

d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

From given,

(x_1, y_1)=(8, 3)\\\\(x_2, y_2) = (2, 11)

Substituting the values we get,

d = \sqrt{(2-8)^2 + (11-3)^2}\\\\d = \sqrt{(-6)^2 + 8^2}\\\\d = \sqrt{36+64}\\\\d = \sqrt{100}\\\\d = \pm 10\\\\Ignore\ negative\ value\\\\d = 10

Thus distance between the given points is 10 units

Answer 2

Answer:

$d = \frac{x1 + x2}{2} \times \frac{y1 + y2}{2}$

$d = \frac{8 + 2}{2} \times \frac{3 + 11}{2}$

$d = \frac{10}{2} \times \frac{14}{2}$

cancelling by 2 table

d =( 5, 7)
