Perimeter of a square= 4 x side

Now, 10 times the perimeter=360 yards

or 10 x( 4 x side)=360 yard

or 40 x side=360 yard

or side=360/40=9 yards

So,

Now, 10 times the perimeter=360 yards

or 10 x( 4 x side)=360 yard

or 40 x side=360 yard

or side=360/40=9 yards

So,

**each side of the square**=**9yards**
