diagonal of a square = √2a
6√2 = √2a. (a = side of square)
6√2/√2 = a
6m = a
therefore, its perimeter = 4×a = 4×6 => 24m
area = a² = 6² = 36m²
hope this helps and ur answer is correct

Shirsa:
6√2=√2a
√2a = 6√2
√2*√a=6*√2
√a=6√2/√2
√a=6
a=36
using Pythagoras theorem , we can take out diagonal of square
diagonal ²= side²+side²
diagonal = √2s² (s= side)
diagonal = s√2
