This is what you should be considering. Take note that integrals for regions below a curve will give you a negative value, so we must extract its value without the negative sign to talk about its area. Here, I do so by introducing modulus to the entire integral for the part below the x-axis.

But sir answer is 10/3
Hmm...
I redo later on a separate piece of paper when I return

Never mind, I am getting paranoid.
I wrote part a as -1/100 (x - 5)^2 + 1/4 correctly.
And I actually wrote -1/100 (x - 5)^2 + 4 in the second part.
I redo everything for you later.
