*** A square has legs that are equal in length .

p/4 = length of a leg

Area = \((p/4)^2\)

= \(p^2 / 16\)

D is the correct answer.

Perimeter of square (sum of all sides) = 4s, where s is the measure of one side.

Hence, p = 4s
p/4= s
Area of square = s^2
(p^2)/16

let side of the square be a and perimeter=p
so a=p/4, so area= a^2, so area=(p*p)/4*4


Option D is correct.

Since the perimeter of the square is p, each side is p/4. Thus, the area is:

(p/4)^2 = p^2/16

Answer: D
