Answer:
GK = 9cm
Step-by-step explanation:
Length of diagonal FH = 9 cm
By the property of a rectangle,
"Lengths of the diagonals of a rectangle measure the same"
FH = GK
Therefore, GK = FH = 9cm
Diagonal of a square is √2a
so,
√2 a = 12
a= 12/√2
and.. perimeter of a square is 4a
so,
peri = 4*12/√2
= 48/√2
=33.94cm
