The length of fenceshadow is 16.25 feet.
In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, tworatios are in proportion when they are equal.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
length of Shadow Height
8 20
12 x
18 y
z 6.5
Using proportion
8/12 = 12 / x
8x = 144
x= 144/8
x= 18
and, 8/ 20 = 18/ y
8y = 360
y = 360/ 8
y = 45
and, 8/20 = z/6.5
130 = 8z
z= 16.25
Hence, the length of fence shadow is 16.25 feet.
