Answer 1

Answer:

6 Feet

Step-by-step explanation:

20% of 5 = 0.2×5 = 1.

The tree has grown, that means 1 foot is added. Hence,

5+1 = 6 Feet.

Answer 2

Tree height after 1 year = 6 ft

Step-by-step explanation:

Jacob planted a 5-foot tree

=> original height = 5 ft

After one year, he measured it and found that the tree had grown by 20% of its original height.

=> Height Increased = (20/100) * 5  = 1 ft

Tree height after 1 year = Original Height + increase in Height

=> Tree height after 1 year =  5 + 1

=> Tree height after 1 year = 6 ft
