Best ResponseYou've already chosen the best response.0Ok, what you have there is two similar triangles (the sides have the same proportions in each). The bigger triangle is \[(6.5+3.5)/3.5\approx2.857\] times bigger than the smaller one. So the height of the tree which is parallel to the metre stick is approx. 2.857 times bigger than the metre stick. So the height of the tree is 2.9 m (1 d.p).
