A tree casts a shadow that measures 5m. At the same time,a meter stick casts a shadow that is 0.4m long. How tall is the tree?
Set it up as a proportion with either both shadow lengths on the top or the bottom.
5/x = .4/1
Multiply top to bottom (5 x 1) then divide by .4 You will then have your answer.
