Let l and w be the length and width of the rectangle. We are given the proportion 2l=4w, which implies l=2w.
The perimeter of a rectangle is given by 2(l+w). We know that the perimeter is 80, and we can plug l=2w to get
Which, in turn, implies that

Answer:
(-2, 0)
Step-by-step explanation:
Use elimination: add the two systems. Because the left is equal to right, you are adding the same thing and it's legal.
-x+3y=2
+ (x+y=-2)
Add each term
-x+x + 3y+y = 2+ -2
4y=0
y=0
x+y=-2
x+0=-2
x=-2
The area of the rectangular garden given the length and width is 16 1/2 square feet
<h3> Area of the garden</h3><h3 />
- Length = 5 1/2 feet
- Width = 3 feet
Area of a rectangular garden = length × width
= 5 1/2 feet × 3 feet
= 11/2 × 3
= 33/2
= 16 1/2 square feet
