Question

Write a formula for the area of a square in terms of the perimeter

Answer 1

Let side of a square be 'a' units
Let the perimeter of that square be 'x' units

$area = {a}^{2} - - - - - (1)$
But,

$x= 4a$
ie
$a = \frac{x}{4} - - - - (2)$
Using (2) in (1)

$area = \frac{ {x}^{2} }{16}$

Answer 2

Answer:

$area = side \times side$
