12.5

15.7

16

16.5

Option 2 - 15.7 unit.    

Step-by-step explanation:

Given :  The image attached.

To find : The perimeter of the following shape?

Solution :

First we determine the coordinate of points,

A=(5,5)

B=(7,3)

C=(3,0)

D=(1,2)

Now, We apply distance formula to find the length of the sides.

The distance between AB,

The distance between BC,

The distance between CD,

The distance between DA,

The perimeter of the given shape is

Therefore, Option 2 is correct.

The perimeter of the given shape is 15.7 unit.
