Having been to Paris, Rob remembered the Eiffel tower, which was the tallest structure in the world at the time it was built in 1887. If the Eiffel tower is 324m tall, how much lower is it compared to today's tallest man-made structure the Burj Khalid? My answer is (1887-324)=1563 m or 2390m tall.
Thanks

what does the year it was built have to do with its height?
I noticed it also. That is how the question was presented. I looked up Burj Khalifa is 2,717 - 324 = 2393.
