Question

a pole of 8.40 height cast a shadow of 4.20.What is the height of another pole if it casts a shadow of length 5.2m​

Answer 1

Answer:

Length of a shadow directly varies to the height of the pole

So y1x1=y2x2 Here x1=8m  y1=10m  x2=? and y2=40m

Substitute 108=40x2 ⇒ x2=108×40=32m

So height of the tree is 32m
