Question 104122: Knowing that a person's height is 5'3, and the distance between the top of his/her head and the eyes is 3 inches, how tall must be the mirror to see the person's entire body, and how high up the wall it must be hanged?
I used this formula{h being the height, and f the distance between the eyes and the top of the head}:h-f1/2=mirror, but I do not think that it works. Would you please help me?

the image of an object reflected in a mirror is half the distance between the object and the eyes

so the length of the mirror is (half the distance from eyes to top of head)+(half the distance from eyes to feet) ... this is half the person's height

the placement of the mirror must be such that the top of the mirror is midway between the eyes and top-of-head
