I couldn't understand the last part, I think they are just options
The last part should be x>-9
Hope it helps!

L = 10a + a
L = 11 a
W = 1/10 (11a)
W = 1.1 a
Perimeter = 2(L + W)
Perimeter = 2*(11a + 1.1a)
Perimeter = 22a + 2.2 a
Perimeter = 24.2 a
Area = L * W
Area = 11a * 1.1a
Area = 12.1 a^2
The perimeter is 2*area
P = 2*A
P = 2* 12.1 a^2
P = 24.2 a^2
Now put in the perimeter on the left side of the above equation.
24.2a = 24.2 a^2 Divide both sides by 24.2
1 a = a^2 Divide by a
1 = a
The length = 11*a = 11*1 = 11
The Width = 1.1 a = 1.1 * 1 = 1.1

9x^4 -225y^8
= 9(x^4 - 25y^8)
= 9(x^2 + 5y^4)(x^2 - 5y^4)
