The owner of a van installs a rear-window lens that has a focallength of -0.301m. When the owner looks out through the lens at a person standingdirectly behind the van, the person appears to be just 0.244 m from the back of the van, and appears to be0.343 m tall.

a) How far from the van is the person actually standing?
b) How tall is the person?
