To find the area of sector \( GPH \), we can use the formula for the area of a sector:

\[ \text{Area} = \frac{\theta}{360} \times \pi r^2 \]

where:

  • \( \theta \) is the angle in degrees,
  • \( r \) is the radius.

From your description, it appears that the radius \( r \) is 15 yards and the angle \( \theta \) is 40 degrees.

Now, substituting the values into the formula:

\[ \text{Area} = \frac{40}{360} \times \pi (15)^2 \]

First, simplify \( \frac{40}{360} \):

\[ \frac{40}{360} = \frac{1}{9} \]

Now calculate \( 15^2 \):

\[ 15^2 = 225 \]

Substitute back into the area formula:

\[ \text{Area} = \frac{1}{9} \times \pi \times 225 \]

\[ \text{Area} = \frac{225\pi}{9} \]

\[ \text{Area} = 25\pi \]

Thus, the area of sector \( GPH \) is

\[ 25\pi \text{ square yards} \]

If you want a numerical approximation, using \( \pi \approx 3.14 \):

\[ 25\pi \approx 25 \times 3.14 \approx 78.5 \text{ square yards} \]

So the area is approximately \( 78.5 \text{ square yards} \).
