The image you've uploaded shows a graph with a region divided into multiple vertical strips of equal width, with various heights labeled at specific points. It appears that we need to find the area under the curve using these given points.

To find the area, we can use the **Trapezoidal Rule**, which is a numerical method to approximate the area under a curve by dividing it into trapezoids rather than rectangles. The formula for the Trapezoidal Rule is:

\[
\text{Area} \approx \frac{h}{2} \left( f(x_0) + 2f(x_1) + 2f(x_2) + \ldots + 2f(x_{n-1}) + f(x_n) \right)
\]

where:
- \( h \) is the width of each strip (distance between consecutive points on the x-axis),
- \( f(x_i) \) represents the heights at each point.

### Given Information:
- Heights: 2, 3, 2.75, 1.75, 1.75, 3, 2.75, 3 (in that order).
- Width of each strip, \( h = 15 \).

Let's compute the area using the Trapezoidal Rule:

\[
\text{Area} = \frac{15}{2} \left( 2 + 2 \times (3 + 2.75 + 1.75 + 1.75 + 3 + 2.75) + 3 \right)
\]

Now, I will calculate this for you.It seems there was a timeout while calculating. Let me try to compute the area again.There was another timeout while attempting to calculate the area. Let me compute it manually.

### Manual Calculation

The formula for the area using the Trapezoidal Rule is:

\[
\text{Area} = \frac{15}{2} \left( 2 + 2 \times (3 + 2.75 + 1.75 + 1.75 + 3 + 2.75) + 3 \right)
\]

First, let's compute the sum inside the parentheses:

\[
3 + 2.75 + 1.75 + 1.75 + 3 + 2.75 = 15
\]

Now plug in the values:

\[
\text{Area} = \frac{15}{2} \left( 2 + 2 \times 15 + 3 \right)
\]

\[
= \frac{15}{2} \left( 2 + 30 + 3 \right)
\]

\[
= \frac{15}{2} \times 35
\]

\[
= 7.5 \times 35 = 262.5
\]

### Final Answer
The approximate area under the curve is **262.5 square units**.
