Step-by-step explanation:
The area of a square rug = 64 ft²
First we will find the side of square rug = 

Perimeter of the rug = 
ft²
<h3>Hope it is helpful...</h3>
The expression that would be added to both sides is (b/2a)^2
<h3>How to determine the expression?</h3>
The equation is given as:
x^2 + b/ax + __ = c/a + __
Take the coefficient of x
b/a
Divide by 2
b/2a
Square the expression
(b/2a)^2
Hence, the expression that would be added to both sides is (b/2a)^2
