Answer:
Square E: s = 5, A = 25
Square F: P = 32, A = 64
Step-by-step explanation:
P = 4s
20 = 4s
s = 5 <-- Answer for side length of Square E
P = 4s
P = 4(8)
P = 32 <-- Answer for the perimeter of Square F
A = s^2
A = 5^2
A = 25 <-- Answer for the Area of Square E
A = s^2
A = 8^2
A = 64 <-- Answer for the Area of Square F
