Question

If the side of a square is $a$, then area and perimeter can be found by using the formulae _____.

• A. $a^2$, 4a
• B. $a^2$, 2a
• C. 2$a^2$, 4a
• D. 2$a^2$,2a

Answer 1

The correct option is A

$a^2$, 4a

Area of square = $sid{e}^2$ = $a^2$

And we know that the perimeter of square = 4 × side = 4a.
