Question

A 10m 50cm high vertical pole cast a shadow of 6m long we need to find lenght of a shawdow cast 5 m 60 cm

Answer 1

8 m 75 cm is the answer

Answer 2

LENGTH OF VERTICAL POLE = 10 m 50 cm or 10.5 m.

SHADOW OF VERTICAL POLE = 6 m.

LENGTH OF ANOTHER VERTICAL POLE = ? (x).

SHADOW OF THIS VERTICAL POLE = 5 m 60 cm or 5.6 m.

THEREFORE, THEY ARE DIRECTLY PROPORTIONAL.

SO,

$\frac{10.5}{6}$ = $\frac{x}{5.6}$

∴ $x$ = $\frac{10.5}{6}$ × $5.6$

⇒ $x$ = $9.8 m$

THE LENGTH OF ANOTHER SHADOW POLE WILL BE 9.8 m..
