Consider there is a direct proportion relation of pole height with pole shadow

So we have 5m 60cm high verticle pole that casts a shadow of 3m 20cm long

hence,

(i) for the length of the shadow cast by another pole of 10 m 50cm high would be 'x' cm

finding x from the equation we get

Therefore for a 10m 50cm pole we would get a shadow of 600cm or 6m length

(ii) The height of a pole which casts a shadow of 5m long let it be 'y'

similar relation holds here also, so we can apply it once more

Thus, the height of a pole which casts a shadow of 5m long is 8m 75cm
