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

D: 65 km²

Step-by-step 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

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

-9
