Question

5b.) Use this equation to write the area A in terms of the perimeter p.

Answer 1

Area of the square will be x^2
And the perimeter is 4x
We know that x = p/4

As area is x^2 , we can substitute the value of p/4 in x place to get:

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

So this is the area A In terms of the perimeter p
