## How Tall Is Your Tree?

Tall Tree

Have you ever wondered how tall the biggest tree in your yard is? There are several methods you can use to measure it, such as cut it down and measure one end to the other. Another would be to send one of the kids shinnying up the tree with one end of a rope and when he falls out of the top measure the length of rope he went up with. Or, if you would rather, you can use your brain and some mathematics.

Here’s an easy way to get the height. Get a partner to stand beside the tree. Stand back from the tree and hold up a 12” ruler out at arm’s length (0 at the bottom, 12 at the top). Move back or forth until to your mind’s eye the tree and ruler are the same length. Hold the ruler steady and see where the top of your partner’s head appears on the ruler. Let’s say it’s at the three inch mark. Dividing 3 into 12 tells you the tree is 4 times taller than your friend. So if your friend is 5 feet tall, then the height of the tree is 20 feet.

Another quick method involves pretending to lay the tree down. Stand back from the tree and hold up a pencil at arm’s length. Move back and forth until to your mind’s eye the tree and the pencil are the same length. Carefully keeping the bottom of the pencil lined up with the bottom of the tree, rotate the pencil 90 degrees until it appears parallel to the ground. Direct a friend to stand at where the top of the pencil appears to touch the ground. The distance from the partner to the tree is its height.
