The answer is b i show the working out in this photo
As diagonals are not perpendicular, it cannot be a square or rhombus (latter does not have congruent diagonals). Hence, quadrilateral is a rectangle.

It will take layla 11 nigths
X+y=8
y=3x
You would want to substitute the y for the 3x
x+3x=8
You can now add the x with the 3x to get 4x
4x=8
Now divide the 4 on both side to solve for x
x=2
Now to solve for y just substitute the x for the 2
y=3(2)
Now multiply the 3 and the 2 to solve for y.
y=6
So your corrct answer is B:(2,6)
