Question

At 1 pm the shadow of a tree is 14 feet long. At the same time the shadow of a 18 foot telephone pole is 21 feet long. What is the height of the tree?

Answer 1

Answer: 12

Explanation:

height/shadow = height/shadow

You get

18/21 =x/14

21 divided by 14 is 1.5

18 divided by 1.5 is 12

So, the answer is 12.

Answer 2

The problem about tree shadows can be solved using ratio and proportion. The solution is as follows:

14/x = 21/18

Cross multiply the equation:

14(18) = x(21)

Solve for x:

x = (14(18))/21
x = 12 ft

Therefore, the height of the tree is 12 feet long.
