Question

This is about similar polygons in geometry

Answer 1

Father's shadow is 9 feet long.

Explanation:

From the given figure,

ΔABC and PQR will be similar.

So their corresponding sides will be proportional.

`(AC)/(PR)=(BC)/(QR)`

`(AC)/(7.5)=(6)/(5)`

AC =
`(6* 7.5)/(5)`

AC = 9 feet

Therefore, measure of the father's shadow is 9 feet.
