  • B
    $8$
  • C
    $16$
  • D
    $64$
✓

Answer

Correct option: A.
$4$
Let the side of square be a
Perimeter is $4a$
Area of square is $a^2$
According to question $4a = a^2$
$\Rightarrow a^2$
$− 4a = 0$
$\Rightarrow a(a - 4) = 0$
either $a = 0 or a =4$
$\therefore 0$ cant be taken as a measure length
