metres. How large will the picture be when the projector is 5 metres from the

When a screen is placed 3 metres from a projector, the picture occupies 3 square
metres. How large will the picture be when the projector is 5 metres from the
screen?
------------------
Both sides of the picture will be 5/3 as big.
3*(5/3)*(5/3) = 75/9
= 25/3 sq meters
