A tree cast a shadow of 18 meters while 3 meter post nearby cast a shadow of 4 meters.what is the height?

Sagot :

N:18=3:4 54=4N N= 13.5 m
for me , my answer is 13.5 meters... i used ratio.. 3/4 x x/18.. then cross multiply... u will get 4x=3(18) then multiply 3 and 18 you well get 4x=54 divide both side by 4  then you well get x=13.5..
hope it help.!
