A shadow stick is a vertical pole placed in the ground. Sunlight casts its shadow on to a level surface below (e.g. a sheet of card or just level ground The length and position of the shadow then depends on both the time of year and the time of day. Local noon can be found from the time when the shadow is shortest. At this time the Sun is highest in the sky and crossing the meridian. However, shadow sticks are not good clocks - the azimuth of the Sun's shadow at a given time changes throughout the year with the Sun's declination. http://www.nmm.ac.uk/server/show/nav.3117

How can you determine how tall a tree is if it casts a shadow that measures 5 m and at the same time a meter stick casts a shadow that is 0.4 m long?

How tall is a tree that casts a 25 foot shadow at the same time a 6 foot stick casts a shadow 4.5 feet long?
A stick is 6/4.5 = 4/3 times its shadow. So the tree is 4/3*25 = 33.3... feet or 33 ft 4 inches tall.

How can we use shadow to tell the time?
You can use a sundial, which is a device that uses the position of the sun's shadow to tell time. By placing a stick or pointer on the sundial, the shadow it casts can indicate the time based on markings on the sundial's face.
I have no idea how to go about this question on my geometry homework! Can someone help me?
The two triangles shown are similar triangles. Numerically, the ratio computed by dividing the length of any side of tower triangle by the length of the corresponding side of the walking stick (similar) triangle will be the same value. Therefore, when the length of the tower shadow is divided by the length of the walking stick shadow, that ratio will be the exactly same as the tower height divided by the walking stick height. (length of tower shadow)/(length of walking stick shadow) = (tower's height)/(walking stick height) tower's height = {(length of tower shadow)/(length of walking stick shadow)}*(walking stick height)
