To determine the area of the section labeled "A1" in the diagram, I'll analyze the image and extract the relevant dimensions.

Let me take a closer look at the image.Based on the image, the dimensions provided for the area labeled "A1" appear to be 3.5 meters by 1.7 meters.

To find the area, you can use the formula for the area of a rectangle:

$\text{Area} = \text{Length} \times \text{Width}$

Substituting the given dimensions:

$\text{Area of A1} = 3.5 \, \text{m} \times 1.7 \, \text{m} = 5.95 \, \text{m}^2$

So, the area of A1 is 5.95 square meters.
