To figure out the height of the building, you need to write a proportion based on similar sides.
Then you solve the proportion by finding the cross products, and dividing my the coefficient with the variable.
The solution is 100 m because the scale factor is 4, and the shadow is four times bigger than the height.
A building casts a 400 meter shadow. You, standing at 2 meters tall, cast a 8 meter shadow. How tall is the building?
2 m
400 m
8 m
