To calculate the perimeter of a trapezoid using the coordinates of its vertices, you first need to determine the lengths of all four sides. Let's assume the coordinates of the trapezoid's vertices are given as points \(A(x_1, y_1)\), \(B(x_2, y_2)\), \(C(x_3, y_3)\), and \(D(x_4, y_4)\).

The length of each side can be calculated using the distance formula:

\[
d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]

You will calculate the lengths of sides \(AB\), \(BC\), \(CD\), and \(DA\) using their respective coordinates:

1. **Length of AB:**
\[
AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]

2. **Length of BC:**
\[
BC = \sqrt{(x_3 - x_2)^2 + (y_3 - y_2)^2}
\]

3. **Length of CD:**
\[
CD = \sqrt{(x_4 - x_3)^2 + (y_4 - y_3)^2}
\]

4. **Length of DA:**
\[
DA = \sqrt{(x_1 - x_4)^2 + (y_1 - y_4)^2}
\]

Finally, the perimeter \(P\) of the trapezoid is given by:

\[
P = AB + BC + CD + DA
\]

Once you calculate each of these lengths, you can sum them up to find the perimeter. After calculating, round the total to the nearest tenth.

In the absence of specific coordinates from the image, I cannot provide an exact numerical answer, but you can apply the above steps once you have those coordinates to find the perimeter and choose the correct answer from the provided options.
