if its diagonal is 10v2 cm.*​

Answer 1

Answer:

hope it helps

Step-by-step explanation:

we know that diagonal of a square is $\sqrt{2} a$

so $\sqrt{2}a = 10\sqrt{2}$cm

a = 10cm

perimeter of a square = 4(side)

4(10) = 40cm

Answer 2

Answer:

Square sides are same

If the side of square is A then as per given condition

A2 + A2= diagonal 2

2 A2= 10 root 2 X 10 root 2

2 A2= 100x2=200

A2= 200/2

A =10 cm

Perimeter= 4 Xsides

               =4 X10 = 40 cm
