after your holiday you have come home and decided that you are going to open up your own business.In order to advertise you put up a free standing sign.
you notice that the shadow of the sign is 4metres long when your shadow is 1.6m long
if you are 1.5m tall,how tallis your sign?

4/h=1.6/1.5
h=6/1.6 check my work. 
1.5/1.6 = x/4
Cross multiply and solve for x. 
4/1.6=1.5/x
x=0.6
