Answer:
y = (x - 4)² - 25
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
y = (x + 1)(x - 9) ← expand factors using FOIL, thus
y = x² - 8x - 9
To complete the square
add/subtract ( half the coefficient of the x- term )² to x² - 8x
y = x² + 2(- 4)x + 16 - 16 - 9
= (x - 4)² - 25 ← in vertex form

I Think The Answer Is -20 Or 66...Because When I Wrote It Out On Paper I Tried To Solve For Me & I Came Up With 66 But When I Wrote It Out Once More I Came Up With -20..Hope I Helped.
20in flat -> 2 sides of 10in at 90degrees from eachother
area would be 10*10/2 =50in^2
