12 foot 6 inches
Background
There are several ways this can be calculated. But first it is helpful to know something interesting about triangles!
If the three internal angles of a triangle are the same as the internal angles of another triangle, both triangles are said to be 'similar', even though one may be bigger than the other. If this is so, then the proprtionate lengths of the sides in one triangle will be the same as the proportionate lengths of the sides of the other triangle.
For examle, if the longest side of triangle 'A' is twice as long as its shortest side, then this ratio will also be true for triangle 'B'.
Some methods
* In the question, in scenario 'A' the longest side is 6 ft, and the triangle height is 5 ft. In scenario 'B' the longest side is 15 ft, which is 2.5 times bigger than scenario 'A', so the new height will also be 2.5 bigger than it was. It was 5 ft, so now it will be 2.5 x 5 = 12.5 ft. * Another way to work it out: The height was 5/6ths of the ladder length. The new ladder length is 15 ft, so the new height will be 15 x 5/6 = 12.5 ft

No, squatting only makes you LOOK shorter in height temporarily.
How many miles tall is the empire state building?
Way shorter than a mile! No building has ever approached that height. A mile is 5,280 feet. The Empire State Building is only 1250 feet. Currently the tallest building, the Taipai 101, is 1671 feet (and 101 floors).

How do you determine the height of an object from free fall?
If the object that falls is sufficiently dense and streamlined, so that the effects of air resistance can be neglected, then you can estimate the height from which it fell like this: -- Time the fall, from the instant the object is released until the instant it hits the ground. -- The distance it fell is [ 16.1 T2 ] feet, or [ 4.9 T2 ] meters. The height of a tall building can easily be measured by using a barometer. There are two convenient methods. 1). Drop the barometer from the roof of the building. Time its fall, from the instant the barometer is released until the instant it hits the ground. The height of the building roof is [ 16.1 T2 ] feet, or [ 4.9 T2 ] meters. 2). Tie the barometer to the end of a long tape-measure or rope. With the barometer as a weight to resist the inaccuracy that would be introduced by the wind, slowly pay out the tape or the rope from the edge of the building's roof, until the barometer just touches the ground. At that point, either read the height directly from the tape, or mark the rope where it touches the roof, and measure the length of rope between the barometer and the mark later.
