Answer:

Option B is correct

the perimeter is,
24+8√(3) units

Explanation:

Let H represents the Hypotenuse side, S represents the shorter side and L represents the side of the longer.

In a 30-60-90 triangle,

The hypotenuse is twice the length of the shorter leg,

and the length of the longer leg is
√(3) times the length of the shorter leg.

As per the statement:

The length of the hypotenuse of a 30 -60 -90 triangle is 16


\text{Length of hypotenuse side} = 16 units.

then by definition of 30-60-90 triangle.


H = 2S


16 = 2S


8 = S

or

S = 8 units

Also. length of the longer leg is
√(3) times the length of the shorter leg


L = √(3) \cdot 8


L = 8√(3) units

Perimeter(P) of a 30-60-90 triangle is sum of all the three sides i.e,


P = L+S+H = 8√(3)+8+16 = 8√(3)+24

Therefore, the perimeter is,
24+8√(3) units
