Answer:
<em>The length of a side of the square is 8 unit.</em>
Step-by-step explanation:
Suppose, the length of a side of the square is
unit.
<u>Formula for perimeter of square</u>: 
<u>Formula for area of square</u>: 
Given that, the area is 32 more than the perimeter. So, the equation will be......

Moving all terms to the left side, we will get.....

Now, factoring out the left side.......

<u>Using 'zero-product property'</u>, we will get......
<em>(Negative value is ignored as the side length can't be in negative)</em>
So, the length of a side of the square is 8 unit.
