Solution

The correct option is A
$100 m^{2}$

It is given that perimeter of a square $= 40 m$
Let $a$ be the side of a square $,$
Perimeter of a square $= 4 a$
$4 a = 40$
$a = 10 m$
Area of a square $= a^{2}$
$= 10 \times 10$
$= 100 m^{2}$
Hence, the area of a square is $100 m^{2}$ therefore option $(A)$ is correct
