b 32
c 36
d 80
click the button or type the letter next to your answer.

Explanation:

Step1: Find the side length of the square

The area formula of a square is \(A = s^{2}\), where \(s\) is the side - length. Given \(A = 64\), then \(s=\sqrt{64}=8\).

Step2: Calculate the perimeter of the square

The perimeter formula of a square is \(P = 4s\). Substitute \(s = 8\) into the formula, we get \(P=4\times8 = 32\).

Answer:

B. 32
