Question

Find the area of the figure. Round your answer to the nearest tenth.

A: 75km^2
B: 43.3km^2
C: 129.9 km^2
D: 65 km^2

Answer 1

D: 65 km²

Explanation:

The formula for area of a hexagon when given the base is

A = (3/2)(√3)b² where b is the length of the base

Here, b is given as 5, plug that in and simplify

A = (3/2)(√3)(5²)

A = (3/2)(√3)(25)

A = (75√3)/2

A ≈ 64.95 ≈ 65
