As we know the ratio of the real height and it's shadow is equal for any body under similar conditions.
So, here
Let height of first as h1 and height of second is 7.5m, shadow of first as S1 and of second as S2.
Now,
h1/S1 = 7.5/S2
h1/7.5 = S1/S2
(S1/S2 is given to us as 2/3, putting it)
h1/7.5=2/3
h1 = 15/3
h1 = 5m
So, here
Let height of first as h1 and height of second is 7.5m, shadow of first as S1 and of second as S2.
Now,
h1/S1 = 7.5/S2
h1/7.5 = S1/S2
(S1/S2 is given to us as 2/3, putting it)
h1/7.5=2/3
h1 = 15/3
h1 = 5m
