Calculating the Height of the Tree

To calculate the height of the tree, we can use the concept of similar triangles. The ratio of the length of the shadow to the height of the object is the same for both the person and the tree.

Given: - Length of the person's shadow = 90 cm - Height of the person = 1.8 m - Length of the tree's shadow = 10 m

We can use the following formula to find the height of the tree: Height of the tree = (Length of tree's shadow / Length of person's shadow) * Height of the person

Calculation

Using the given values: Height of the tree = (10 / 0.9) * 1.8

Height of the tree = 20 * 1.8

Height of the tree = 36 meters

So, the height of the tree is 36 meters.
