Step-by-step explanation:

diagonal = 10 cm

all the sides of a square are equal and each interior angle is 90 degrees.

two adjacent sides and a diagonal will form right triangle .

By, pythagoras theorem,

10*10=side*side + side*side

100=2*side*side

side=5 * root 2

perimeter = 4*5 * root 2=20*root 2
