Answer:
Width of the land can be represented by either (x - 5) or (x + 6).
Step-by-step explanation:
The office and parking lot are on a rectangular piece of land.
Area of a rectangular area = Length × Width
Expression for the area has been given as x² + x - 30
Now we will factorize the given expression.
x² + x - 30 = x² + 6x - 5x - 30
= x(x + 6) - 5(x + 6)
= (x - 5)(x + 6)
So the area of the rectangular lot = (x - 5)(x + 6) = Length × width
Therefore, width of the land can be represented by either (x - 5) or (x + 6)
