To find the surface area of the net, we need to find the area of each individual triangle that makes up the net and then add them together.
First, we find the area of the equilateral triangle in the middle:
A = (1/2) x base x height
A = (1/2) x 16.2 x 14
A = 113.4 square meters
Next, we find the area of the two triangles on the sides:
A = (1/2) x base x height
A = (1/2) x 16.2 x 14.5
A = 117.45 square meters (for each triangle)
Now, we add the areas of all three triangles together:
Total surface area = 113.4 + 117.45 + 117.45
Total surface area = 348.3 square meters
Therefore, the surface area of the net is 348.3 square meters.
