Certainly! To find the area of a rectangular yard, we need to multiply its length by its width. The length of the yard is given as \(\( 4x - 1 \)\) and the width is \(\( 2x + 7 \)\).

Let's calculate the area step by step:

1. Write down the expressions for the length and width:
- Length \(\( L = 4x - 1 \)\)
- Width \(\( W = 2x + 7 \)\)

2. Set up the expression for the area \(\( A \)\) of the rectangle:
- The area \(\( A \)\) is given by the product of the length and the width:
\(\[ A = L \times W \]\)

3. Substitute the expressions for \(\( L \)\) and \(\( W \)\) into the area formula:
\(\[ A = (4x - 1) \times (2x + 7) \]\)

4. Expand the expression:
- This can be done using the distributive property (also known as the FOIL method for binomials):
\(\[ A = (4x - 1)(2x + 7) \]\)

So the area of the rectangular yard can be expressed as:
\(\[ (2x + 7)(4x - 1) \]\)

Therefore, the area of the yard given the length \(\( 4x - 1 \)\) and the width \(\( 2x + 7 \)\) is \(\( (2x + 7)(4x - 1) \)\).
