let's recall that a square has four equal sides, so if one side is x + 4½ long, then all four are x + 4½ long, and the perimeter is simply the sum of all four.

let's first off, convert the mixed fraction to improper fraction.



\bf \stackrel{mixed}{4(1)/(2)}\implies \cfrac{4\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{9}{2}} \\\\\\ \left( x+\cfrac{9}{2} \right)+\left( x+\cfrac{9}{2} \right)+\left( x+\cfrac{9}{2} \right)+\left( x+\cfrac{9}{2} \right)\implies 4\left( x+\cfrac{9}{2} \right) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill 4x+18~\hfill

Answer: Perimeter of square would be 4x+18 units.

Explanation:

Since we have given that

Length of square =
x+4(1)/(2)

So, after simplification, we get that


x+(4* 2+1)/(2)\\\\=x+(9)/(2)

As we know the formula for "Perimeter of square";

Perimeter of square is given by


4* side\\\\=4* (x+(9)/(2))\\\\=4x+4* (9)/(2)\\\\=4x+(36)/(2)\\\\=4x+18

Hence, Perimeter of square would be 4x+18 units.
