Let’s solve this step by step.
We are given a regular hexagon (6 sides), and each side is 5 units long.
We’re also told the apothem (the distance from the center to the middle of a side) is 4.33 units.
The formula for area of a regular polygon is:
>
A = ½ × perimeter × apothem
---
Step 1: Find the perimeter
Perimeter = number of sides × length of one side
→ Perimeter = 6 × 5 =
30
---
Step 2: Plug into the formula
A = ½ × 30 × 4.33
First, ½ × 30 = 15
Then, 15 × 4.33
Let’s calculate that:
15 × 4 = 60
15 × 0.33 = 4.95
So, 60 + 4.95 =
64.95

Double-check with direct multiplication:
15 × 4.33
= 15 × (4 + 0.3 + 0.03)
= 15×4 = 60
15×0.3 = 4.5
15×0.03 = 0.45
Total = 60 + 4.5 + 0.45 =
64.95
✔ Correct.

Final Answer:
64.95
