Illusion [34]

Given:

Height of Isabelle = 62 inches

Shadow of Isabelle = 93 inches

Shadow of tree = 279 inches

To find:

The height of the tree.

Solution:

Let height of tree be x.

Ratio of height to shadow for Isabelle and tree are

\dfrac{\text{Height of Isabelle}}{\text{Shadow of Isabelle}}=\dfrac{62}{93}

\dfrac{\text{Height of tree}}{\text{Shadow of tree}}=\dfrac{x}{279}

The shadow of Isabelle and tree are proportional to their shadows. So, both ratios must be equal.

\dfrac{x}{279}=\dfrac{62}{93}

Multiply both sides by 279.

x=\dfrac{62}{93}\times 279

x=62\times 3

x=186

Therefore, the height of tree is 186 inches.
