Answer:
7.06
Step-by-step explanation:
This triangle can be solved a couple of ways. In the end, they amount to the same thing.
1) The area is ...
A = 1/2bh = 1/2(8)(15) = 60 . . . using DG as the base
Using GE as the base, the height (DF) is ...
A = (1/2)(17)(DF)
2(60)/17 = DF = 120/17
DF ≈ 7.06
__
2) Using similar triangles, we can find the ratio of the long side to the hypotenuse as ...
(long side)/(hypotenuse) = DE/GE = DF/DG
DF = DG(DE/GE) = 8(15/17) = 120/17
DF ≈ 7.06
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.

Step-by-step explanation:
Answer:

Step-by-step explanation:
the third option
Area of the triangle = 1/2 * base * <span>height
base = 16 in
</span>height = 16 in
Area = 1/2 * 16 * 16 = 128 in.
