Answer:
Option D is correct.
Explanation:
It is given that 6 feet tall casts shadow for 38 feet long.
We need to find the shadow f 986 ft tall Eiffel tower.
Let's set up proportional equation to solve. Let the shadow length as 'x' feet for the tower.

Cross multiply,
6 x= 37468
Divide both sides by 6.
x= 6244.67 feet approximately.
If we round it to nearest feet, we get 6245 feet.
