Measure height and shadow af a smaller object --- call these h1 and s1
measure the shadow of something larger like a tree. call this s2 its height is the unknown call it h2
use a proportion to solve the problem
h1/s1 = h2/s2 substitute in the measured amounts, rearrange the equation (proportion) and find the answer.

What will be the height of the shadow cast by a person standing near a 20 ft light post.The height of the person is 6 ftThe distance between man and pole is 10 ft?
It is zero: 0cm; 0mm A shadow has no height: length yes, but height no
What is the height of the shadow when the distance from the object to the screen is 60 cm ............................?
More information, or an image, is required to answer this question.
What tool do you use to measure the height of a school?
(1) One way would be to have a stick, stuck vertically into the ground. Measure the length of the shadow and the length of the stick. The actual height of the stick will be a ratio of the shadow's length. Then measure the length of the school's shadow. The height of the school in comparison with its shadow length will be same ratio as the height of the stick compared to its shadow length. You could use a tape measure for this. And possibly a calculator, which will make the calculation easier than doing it by long arithmetic or mental arithmetic. (2) Another way would be to use something that can tell you, from a short distance away from the school, the angle between the top of the school and the ground. A sextant can do this. It is more accurate than using a protractor. Using trigonometry and the distance from the building to where you are standing, you will be able to calculate the height of the school, because it will be at right angles to the line from you to the school. If you don't know trigonometry, method (1) will be easier.
When is our height shorter to our shadow?
When the sun is low down, the shadow is longer. If the sun is high up the shadow is shorter.
What is the height of a building that cast a 105' shadow when a 6' man casts a 14' shadow?
Height of building/105 = 6/14 Multiply both sides by 105: Height = 630/14 Height = 45 feet
