To find the area of sector GPH with a radius of 12 yards and an angle of 20 degrees, you 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.

For your specific values:

  • \(\theta = 20\) degrees,
  • \(r = 12\) yards.

Now, plug in the values:

\[ \text{Area} = \frac{20}{360} \times \pi \times (12)^2 \]

First, calculate \(12^2\):

\[ 12^2 = 144 \]

So now we have:

\[ \text{Area} = \frac{20}{360} \times \pi \times 144 \]

Next, simplify \(\frac{20}{360}\):

\[ \frac{20}{360} = \frac{1}{18} \]

Now substitute this back into the equation:

\[ \text{Area} = \frac{1}{18} \times \pi \times 144 \]

Now calculate:

\[ \frac{144}{18} = 8 \]

Thus, the area becomes:

\[ \text{Area} = 8\pi \]

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

\[ \text{Area} \approx 8 \times 3.14 \approx 25.12 \text{ square yards} \]

So, the area of sector GPH is:

\[ 8\pi \text{ square yards} \quad \text{or} \quad \approx 25.12 \text{ square yards} \]
