Using the perimeter of the rectangle, it is found that she should buy at most 16 plants.
---------------------------
The perimeter of a rectangle of length l and width w is given by:
In this question, the perimeter is of 1 ft by 4.5, thus, 
, and the perimeter is:
- Perimeter of 11 ft.
- The plants will be at least 8 inches = 2/3 feet apart along the perimeter, thus:
1 plant - 2/3 ft
x plants - 11 ft
Applying cross multiplication:
At least 8 inches apart(can be more), thus she should buy at most 16 plants.

Answer:
540 ft^2.
Step-by-step explanation:
The area of the trapezoid = h/2 (10 + 18) = 14h.
By Pythagoras the height h = √(5^2 - 4^2) = 3.
So the area of the 2 trapezoidal bases = 2 * 14*3
= 84 ft^2.
Now we calculate the area of the four lateral rectangular sides:
= 10*12 + 18*12 + 2*5*12
= 456 ft^2.
Total area = 456 + 54
= 540 ft^2.
