Given
The length of two vertical post is 2meters and 0.45 meter respectively.
And, the length of shadow of the shorter post is 0.85meter.
To find:
The length of the shadow of the longer post.
Explanation:
It is given that,
The length of two vertical post is 2meters and 0.45 meter respectively.
And, the length of shadow of the shorter post is 0.85meter.
That implies,
Then,
[tex]\begin{gathered} \frac{2}{0.45}=\frac{x}{0.85} \\ x=\frac{2\times0.85}{0.45} \\ x=\frac{1.7}{0.45} \\ x=3.78m \end{gathered}[/tex]Hence, the length of the shadow of the longer post is 3.78m.
