Respuesta :

The height of the tree is 80 feet

How to determine the height of the tree?

The given parameters are:

  • Building = 40 ft
  • Shadow of the building = 9 ft
  • Shadow of the tree = 18 ft

The above parameters can be represented as:

Building : Shadow of the building = Tree : Shadow of the tree

This gives

40 : 9 = Tree : 18

Express as fraction

40/9 = Tree/18

Multiply both sides by 18

Tree = 80

Hence, the height of the tree is 80 feet
