To find the area of a parallelogram, you can use the formula:
\[ \text{Area} = \text{base} \times \text{height} \]
In this case, you provided two dimensions: 12 ft and 7 ft. We will assume that 12 ft is the base of the parallelogram, and 7 ft is the height.
Now, substitute the values into the formula:
\[ \text{Area} = 12 , \text{ft} \times 7 , \text{ft} = 84 , \text{ft}^2 \]
So, the area of the pool will take up 84 square feet in the yard.
