Answer:
The third one

18 meters by 14 meters
Area of rectangle is base times height (AKA length times width or however you wish to call the dimensions).
This question is a system of equations question. We can make two equations. We know that every rectangle must have 2 "lengths" and 2 "widths" (4 sides in a rectangle). Since Maria only has 64 meters of fencing, we get the equation:
2L+2W = 64
Now we know the area enclosed must be 252 so we have:
L* W = 252
Rewriting the second equation we get:
Plug this into first equation to get:
(multiply everything by L)
Solving the quadratic tells us L can be 18 or 14. Let's consider if L is 18 first by plugging 18 back into the second equation to get 18 * W = 252 which gives us W = 14. If we do the same for when L = 14, we get that W = 18.
Now you might wonder why we have 2 possible combinations, that's because in reality, it doesn't matter which one we label as length (L) or width (W).
Step-by-step explanation:
plug in 1 and 4 for x and y
(4)=2(1)-5
then do the math
4=2-5
4 does not equal -3 therefore it is not a solution
However, point slope equations can be awkward to use in some algebraic operations. In such cases, it may be helpful to convert the equation into a different form, the standard form. The standard form of an equation is Ax + By = C. In this kind of equation, x and y are variables and A, B, and C are integers.

The critical values
It is in the region of dismissal. We dismiss the 10% significant null hypothesis.
P - value is greater than the level of significance a= 0.05
Null hypothesis we don't reject. At a 95% level, the claim is justified.
P - value below the meaning level a = 0.10, we reject the hypothesis null. At a level of 90% the claim is not justified.
