Question

A tall tree casts a shadow that is 30 meter long. At the same time, Nikki is 2 meters tall and casts a 3 meter shadow. How tall is the

Answer 1

tree?

We can set up a proportion to solve for the height of the tree:

height of tree / length of tree's shadow = height of Nikki / length of Nikki's shadow

Let x be the height of the tree. Then the proportion becomes:

x / 30 = 2 / 3

Cross-multiplying, we get:

3x = 60

Dividing both sides by 3, we get:

x = 20

Therefore, the height of the tree is 20 meters.
