Answer:
X position is h = -b / 2*a
h = - -4 / 2 * 1
h = 2
k (or y) = ah^2 + bh + c
= 1 *4 + -4*2 * 2 -7
= 4 -8 -7
= -11
So vertex = (2, -11)

Step-by-step explanation:
Let the breadth be x m.
So, length = 4x m.
Area of the rectangle = 1936m sq.
So,
4x × x = 1936
4x^2 = 1936
x^2 = 1936/4
x^2 = 484
x = √484
x = √22×22
x = 22
Hence, breadth = 22m.
Length = (4×22)m = 88m.
