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.
