Answer:
Area, A(x) = 26x - x² , as a function of the length (x).
Explanation:
Yardbird Landscaping has 52 m of fencing with which to enclose a rectangular garden.
Let x be the length of garden
So perimeter of rectangle = 52 m
Perimeter = 2 x ( Length + width)
52 = 2 x ( x + width)
Width= 26 - x

Area, A(x) = 26x - x² , as a function of the length (x).
