Length of person whose shadow is cast 4 feet tall is 3 feet as a 15-foot statue casts a 20-foot shadow using proportion.
A proportion is a form of ratio in which the denominator also contains the numerator. For example, the fraction of male deaths would be deaths to men divided by deaths to males + deaths to females (i.e. the total population). A proportion is a component, piece, or amount that is compared to a total. It might be 0 or 1, or any number between 0 and 1. It can be stated numerically or as a percentage.
Here,
length of statue=15 feet
length of shadow of statue=20 feet
length of shadow of person = 4 feet
so, length of statue be x,
20/15=4/x
20x=15*4
20x=60
x=3 feet
