Answer:
A =256 mm^2
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
|14.06| =
14.06*14.06=197.6836
both will be positive
