Given : The sun casts a shadow that is proportional to the object’s height. The height of a pole is unknown. Its shadow is 7 ft.
The height of a nearby tree is 8 ft. Its shadow is 28 ft.
To Find : the unknown length of Pole.
Solution:
The sun casts a shadow that is proportional to the object’s height.
=> Height of tree/ Shadow of Tree = Height of pole / Shadow of Pole
=> 8 / 28 = Height of pole / 7
=> Height of pole = 7 * 8 /28
=> Height of pole = 56 /28
=> Height of pole = 2 ft
the unknown length of Pole = 2 ft
