Question

Area of a square is $625m^2$. Find its perimeter.

• A. $25m$
• B. $50m$
• C. $100m$
• D. $10m$

Answer 1

Answer: (C)

$100m$

Let $a$ be the side of the square.

Area of a square $a^2=625m^2$

$\Rightarrow a^2=25\times 25$

$\therefore$ Side $=\sqrt{625}=25m$

Hence,

Perimeter $=4\times$ (Side) $=4\times 25=100m$
