## Answer :

**Step-by-step explanation:**

__Sure! To find the new height of the tree, we can calculate the increase by multiplying the current height (4.8 m) by the percentage increase (12.5%) and then adding it to the current height.__

__Increase = 4.8 m * 12.5% = 0.6 m__

__New height = Current height + Increase = 4.8 m + 0.6 m = 5.4 m__

__So, the new height of the tree after one year is 5.4 meters.__

__Let me know if there's anything else I can help you with! __

**Answer:**

To find the new height of the tree after increasing by 12.5%, follow these steps:

1. Calculate the increase in height: 12.5% of 4.8 meters.

2. Add the increase to the original height to find the new height.

Let's do the calculations:

1. Increase in height:

\( 12.5\% \) of \( 4.8 \) meters \( = 0.125 \times 4.8 = 0.6 \) meters.

2. New height:

Original height \( + \) Increase in height \( = 4.8 \, \text{m} + 0.6 \, \text{m} = 5.4 \, \text{m} \).

So, the new height of the tree is \( 5.4 \) meters.
