The tree is 820 inches tall using the similarity of triangles.
To get the height of the tree, we will use the properties of similar triangles expressed as:

- Note that 1 foot = 12inches
- 7ft = 84in and 82ft = 984in
- h is the required height of the tree. Simplify the equation above to get the height "h" and replace feet with inches;

Hence the tree is 820 inches tall using the similarity of triangles.
