Diagonal = 5 to the root 2
Area of square by its diagonal = d square divided by 2
= 5root2 square / 2
= 25*2/2
= 25 unit square
Therefore area of square = 25 unit square
Let's find side
Area of square = side^2
= 25^2
= 5 units
We have now side as 5 units
Therefore perimeter = 4* side
= 4* 5
= 20 units
I hope it helped you
