Find the perimeter of the following shape, round to the nearest tenth

The perimeter of the figure is:

                       17.9 units

We know that the perimeter of the figure is the sum of all the side lengths of a figure i.e. it is the sum of the distance around a figure.

In the given figure the perimeter of the figure is:

Length AB+Length BC+Length CD+Length AD

Now from the figure we see that:

A is located at  (-3,5)

B is at (1,7)

C is located at (3,3)

and D at (-1,1)

Hence, by using distance formula we get:

and

Hence, we get perimeter of figure is:

Hence, to the nearest tenth we have:

      Perimeter=17.9 units

the last choice
