Question

A tree casts a shadow 13 ft long. A boy standing next to the
tree casts a shadow 4 ft long. If the boy is 6 ft tall, how tall is
the tree?

Answer 1

Answer:

19.5 ft

Step-by-step explanation:

Let the Height of the tree be y.

Shadow of the boy = 4 ft

Actual height of the boy = 6 ft

Shadow of tree = 13 ft

Therefore, 4/6 = 13/y

4y = 6 x 13

4y = 78

y = 78 divided by 4

y = 19.5

Therefore, the height of the tree is 19.5 ft

or

The tree is 19.5 ft tall
