Answer:

is not a rectangle

Step-by-step explanation:

The midpoints of the diagonals are ...

AC midpoint = ((2, -2) +(11, 13))/2 = (13/2, 11/2)

BD midpoint = ((14, 10) +(-2, 1))/2 = (6, 11/2)

The midpoints of the diagonals are different, so this is not a rectangle or any sort of parallelogram.

Maslowich

In kilometers, the approximate distance to the earth's horizon from a point h meters above the surface can be determined by evaluating the expression

$d= \sqrt{12h}$

We are given the height h of a person from surface of sea level to be 350 m and we are to find the the distance to horizon d. Using the value in above expression we get:

$d= \sqrt{12*350}=64.81$

Therefore, the approximate distance to the horizon for the person will be 64.81 km
