Question

a tree casts a shadow of 25 meters while a 2 meter post nearby casts a shadow of 3 meters how tall is the tree

Answer 1

16.67 m

Explanation:

Use a proportion.

Let x = height of tree.

2 m post is to 3 m shadow as an x meter tree is to a 25 m shadow.

2/3 = x/25

Cross multiply and solve for x.

3x = 2 × 25

3x = 50

x = 16.67

Answer: 16.67 m
