Width=20.108 yrd and Length=43.216 yrd
Step-by-step explanation:
Let width = w
Length =3+2w
Area = 869 yrd^2
We need to find length and width of rectangle.
The formula used is:
Putting values:
Using quadratic equation to find value of width w:
a=2, b=3 and c=-869
Since width can't be negative so, width w=20.108
Length will be: L=3+2w = 3+2(20.108)=3+40.216=43.216
So, Width=20.108 yrd and Length=43.216 yrd

now, the angle of θ, can only have a "y" value that is positive on, well, y is positive at 1st and 2nd quadrants
and "x" is positive only in 1st and 4th quadrants
now, that angle θ, can only have those two fellows, "y" and "x" to be positive, only in the 1st quadrant, and also both to be negative on the 3rd quadrant.
and that those two fellows, can also be both negative in the 3rd quadrant
3/1 = 3, and -3/-1 = 3
so, the solutions can only be "3", when both "y" and "x" are the same sign, and that only occurs on the 1st and 3rd quadrants
