Mathematical Constraints in Landscaping Dimensions
A landscaping contractor is calculating the dimensions for a 150 square foot rectangular turf area where the length is one foot less than three times the width. The contractor identifies that the discriminant of the resulting quadratic equation is 1801. According to the problem-solving strategy, what is the specific mathematical reason that these dimensions must be provided as rounded decimals rather than exact whole numbers?

A landscaping contractor is calculating the dimensions for a 150 square foot rectangular turf installation where the length is one foot less than three times the width. Arrange the following steps in the correct order to solve this problem.
A landscaping contractor is calculating the dimensions for a 150 square foot rectangular turf area where the length is one foot less than three times the width (w). This results in the standard form equation: 3w^2 - w - 150 = 0. Match each part of the quadratic setup to its correct value.
A landscaping professional is using the Quadratic Formula to find the width of a 150 square foot rectangular turf area. If the formula produces two solutions, one positive and one negative, what action should be taken according to the standard problem-solving strategy?
Mathematical Constraints in Landscaping Dimensions
If the discriminant of a quadratic equation used to find the dimensions of a rectangular turf area is not a perfect square, the resulting solutions are irrational and must be approximated for practical use.
In a professional landscaping project for a 150-square-foot turf area, the width is calculated using the quadratic equation $3w^2 - w - 150 = 0$. After determining the discriminant is 1801, the designer recognizes that because 1801 is not a(n) ____ ____, the resulting dimensions will be irrational and must be rounded for practical use.
