half perimeter = 12.
so full perimeter= 12 ×2= 24
perimeter of square = 4 × side
24 = 4 × side
so side = 24 / 4
= 6
then ,
area= side × side
= 6 × 6
= 36
so full perimeter= 12 ×2= 24
perimeter of square = 4 × side
24 = 4 × side
so side = 24 / 4
= 6
then ,
area= side × side
= 6 × 6
= 36

Answer:36cm²
Step-by-step explanation: half of the perimeter of a square= 12 cm
full perimeter of a square= 12+12=24cm
Perimeter of a square=a+a+a+a (or)a×4
24cm=4a
a=24/6
that's why one side=6cm
Area of a square= 6×6
=36cm²
