Answer:
16 x units
Step-by-step explanation:
Perimeter of a original square= 8 x units
Perimeter of a square= 4× side
Side of a square = [tex]\frac{perimeter}{4}[/tex]
Side of a square = [tex]\frac{8x}{4}[/tex]
Side of a square= 2 x units
since four square are joined together to form a single square
So each side of a bigger square= 4 x units
Perimeter of a new bigger square= 4 × 4 x units
Perimeter of a new bigger square= 16 x units
Hence, the correct answer is 16 x units
