A man is six feet tall and casts a shadow 4 feet long. At the same time a child is 4.5 feet tall, how long is her shadow?
Cross multiply and solve for x.
6/4 = 4.5/x
x = 3 feet long
Thats an easy one it's three.
To find the length of the child's shadow, you can set up a proportion using the height and shadow length of the man.
Let's call the length of the child's shadow "x". The proportion can be written as:
6 feet (height of the man) / 4 feet (length of the man's shadow) = 4.5 feet (height of the child) / x (length of the child's shadow)
Now, cross-multiply and solve for "x":
6 feet * x = 4.5 feet * 4 feet
6x = 18 feet
x = 18 feet / 6
x = 3 feet
Therefore, the length of the child's shadow is 3 feet.
