Question

At a particular time the length of shadow is Qutub Minar whose height is 72 metre, is 80m. What will be the height of the electric pole the length of shadow at the same time is 1000cm?​

Answer 1

let the height of the electric pole be x m

here shadow of the electric pole is 1000 cm=10m

(as 1 m= 100 cm)

now,

let's assume that the electric pole and qutub minar are parallel to each other and perpendicular to the ground .therefore, both of them form right angled triangles.

then,

72/80= x/10 (proportional sides )

solving,

9=x

Therefore, the height of the electric pole is 9m.
