10 knots. 5 knots above and 5 knots below are added to equal 10 knots.
5(x + y) - 3(x - y)
5x + 5y - 3x + 3y
5x - 3x + 5y + 3y
2x + 8y
5(x + y) - 3(x - y) = 2x + 8y

Step-by-step explanation:
The perimeter of a square is given by the formula
P = 4s where s is the length of a side
64 = 4s
Divide each side by 4
64/4 =4s/4
16 = s
To find the area of a square, use the formula
A =s^2
A = 16^2
A =256 mm^2
