<span>For all rectangles with a fixed perimeter of p the rectangle with the maximum area is one where the length is p/4 and the width is p/4, in other words a square. The area of such a rectangle would be (p*p) /16.</span>
Answer: The width is 12 feet shorter than the length.
Step-by-step explanation:
The area of a rectangle can be calculated with this formula:

Where "l" is the lenght and "w" is the width of the rectangle.
We know that lenght of Jennie's yard is 30 feet, the width is
and the area is 540 square feet. Then:

Substitute these values into the formula and then solve for "x":

Therefore, the width is 12 feet shorter than the length.

Answer:
f(x) = x² - 13x + 42
Step-by-step explanation:
given zeros are x = 6 and x = 7 then the corresponding factors are
(x - 6) and (x - 7)
the quadratic function is then the product of the factors , that is
f(x) = (x - 6)(x - 7) ← expand using FOIL
= x² - 13x + 42
