Answer 2

Answer:

Step-by-step explanation: i can use here the unitary method

so..  

 no. of years -   5      30

  feet             -    3        x

  i will cross multiply it

so  5x=30x3                                                                                                                                         5x=90

90/5=x

18=x

hence the height in 30 years will be 18 feet
