X^2 + 6x - 5 = 0
2 numbers that multiplied give you 5
those 2 numbers have to add up to 6
1 x 5 = 5
1+ 5= 6
(x + 1) (x+ 5)
x= -1, -5
the opposite of the parenthesis

Step-by-step explanation:
If you create a 5x5 square in the most square part of the figure you are left with 4 squares not calculated inside the figure and 8 outside of the square, that means that roughly you have a 5x5 square and 4 more squares outside the big square that would made for 625 mi2.
