a) Area = 60W - W²
b) For maximum area, W = 30 yards
c) Maximum area = 900 yard²
Step-by-step explanation:
Diana has available 120 yards of fencing and wishes to enclose a rectangular area.
Let L be the length and W be the width.
Perimeter of rectangle = 2 ( L + W) = 120
L + W = 60
L = 60 - W
a) Area, A = Length x Width = (60 - W) x W = 60W - W²
b) For maximum area we have
For maximum area, W = 30 yards
c) Area = 60W - W² = 60 x 30 - 30² = 900 yard²
Maximum area = 900 yard²
