Answer:
111 Feet
Explanation:
The feet of antique picket fencing are to be used to enclose the garden is equivalent to the perimeter of the flower garden.
The perimeter P of a rectangle whose length is L and width is W is given as
P = 2( L + W)
Given that the width is exactly two-thirds of the length
then, W = 2/3 L and P = 370 feet
L = 3/2 W = 1.5W
370 = 2 ( 1.5W + W)
370 = 5W
W = 370/5
= 74 Feet
L = 1.5W
= 1.5 * 74
= 111 Feet
