Shadow
Shadow problems are specialized variations of Ratio problems. The wording usually
contains the sequence of words like:
<first object> m feet tall casts a shadow n feet long.
How long does a <second object> x feet long.
m, n, and x are numbers.
The equation to be developed is:
Height of <first object> Height of <second object>
----------------------------- = ---------------------------------
Shadow length of <first object> Shadow length of <second object>
It is important that the left and
right sides of the proportion be consistent. Height
over Shadow on each side. Although there are other ways to write the proportion, we will
stick to this format.
