Answer:
To calculate the object or image height, you can use the following formula:
height = (distance x size) / focal length
where:
distance: object distance or image distance, depending on which height you want to calculate
size: object size or image size, depending on which height you want to calculate
focal length: the focal length of the lens or mirror
If you have the object distance and size, you can calculate the object height using the formula above. If you have the image distance and size, you can calculate the image height using the same formula.
