Question

Perimeter of a square is $4$ more than the area of a square, then find length of its side.

• A. $5$ units
• B. $4$ units
• C. $3$ units
• D. $2$ units

Answer 1

Answer: (D)

$2$ units

Let length of side be 'a', the n

Area$=a^2$ and Perimeter$=4a$

$4a-a^2=4\Rightarrow a^2-4a+4=0\Rightarrow {(a-2)}^2=0$

$a-2=0\Rightarrow a=2$ units
