Abuilding casts a shadow 46 feet long. at the same time, a 42‐foot‐tall flagpole casts a shadow 9.2 feet long. what is the height of the building

The height of the building is 210 feet.

Explanation

A 42 feet tall flagpole casts a shadow 9.2 feet long. That means, the ratio of the length of flagpole to the length of its shadow will be:  

Now, a building casts a shadow 46 feet long. Suppose the height of the building is feet.

As the ratio will be same for Flagpole and Building at same time, so....

So, the height of the building is 210 feet.

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5
