$\huge{\underline{\underline{\star{\mathfrak{answer}}}}}\star$

1 km = 1000 m

48.4 km = 48400 m

Perimeter of Square = 4 × side

48400 = 4 × side

$\dfrac{48400}{4}$ =side

12100 m = side

1 m = $\dfrac{1}{1000}$ m

12100 m = $\dfrac{12100}{1000}$ m

= 12.1 km

side in metres = 12100 m

side in km = 12.1 km
