Given that the height of the tallest building in Anne's home town = 617 ft
We have to find the height of the tallest building in Laurie's home town.
So let the height of the tallest building in Laurie's home town = x
Now question says that the tallest building in Anne's home town is about 233 ft taller than the tallest building in Laurie's home town. So we can write:
Anne's Home Town = Laurie's home town + 233
617 = x + 233
617 - 233 = x
384 = x
Hence final answer is the height of the tallest building in Laurie's home town = 384 feet.
