If the shadow of a tree is 14 m long and the shadow of a person who is 1.8 m tall is 4 m long, how tall is the tree?

tigry1 [53]

Ratio and proportion

real:shadow

so the person is 1.8m but the shadow is 4m
so
real:shadow=1.8:4

so
1.8:4=?:14
1.8/4=?/14
times both sides by 14
25.2/4=?
6.3=?

the tree is 6.3 m tall
