Answer:
Step-by-step explanation:
Area of Square = (x+5)²= x² + 10x + 25
Area of rectangle = 2x * x = 2x²
area of rectangle + 1 = Area of square
2x² + 1 = x² + 10x +25
2x² + 1 - x² - 10x - 25 = 0
x² - 10x - 24 = 0
(x - 12) (x + 2) = 0
x - 12 = 0 ; Ignore x + 2 because length wont come in negative
x = 12
- - Let's solve for C.
