Answer:

B. 40 cm
Step-by-step explanation:
Small squares area is 25. Find it square root and it's the length of smaller squares which is 5. Since it's 2 small squares in a row, multiply it to the length of the smaller squares to know the length of the big square.
5 × 2 = 10
The length of the side of the big square is 10 cm.
Perimeter of the Square = 4a
P = 4 (10)
P = 40
Perimeter of the big square is 40 cm.
