Answer:

Bird house is 20 ft. high.

Step-by-step explanation:

Let the height of the bird house is h feet high casts a shadow of 14 ft long.

My friend is 5 feet high and casts a shadow of 3.5 feet.

Now we see both the triangles Δ ABC and Δ XYZ are similar.

By the similar triangles theorem sides opposite to the corresponding angles will be in the same ratio.

$\frac{5}{h}=\frac{3.5}{14}$ (from similar triangles ABC and XYZ)

$h=\frac{14\times5}{3.5}=\frac{70}{3.5}=20 ft.$

Therefore bird's house is 20 feet high.
