Use Ratios to Find the Height of a Building in Two-Point Perspective
Problem Statement:
The pre-placed blocks draw two buildings with proportional width and height. Use the given widths of the buildings and the height of highlighted side of the larger building to find the height of the corresponding side of the smaller building.
