Question

14. The first tree on the left is 8cm tall and is 30cm from the vanishing point. If the third tree is 20em from the

vanishing point, how tall is it?

d.

160 cm

8 cm

C.

b. 0.1875 cm

a.

5.3 cm

Answer 1

5.3cm

Explanation:

Step one:

given data

First tree

the tree is 8cm tall

and 30cm from the vanishing point

Third tree

let the tree be x cm tall

and 20cm from the vanishing point

Step two:

if 8cm tree will be 30cm at the vanishing point

then x cm tree will be 20cm at the vanishing point

cross multiply we have

x= (20*8)/30

x=160/30

x=5.3cm

The third tree is 5.3cm tall
