Question

If the area of a square is quadrupled, how will its perimeter change? ( A ) half ( B ) double ( C ) quadruple ( D ) triple

Answer 1

Answer:

B) double

Step-by-step explanation:

Area of a square =

$a { }^{2}$

Perimeter = 4a

Area is quadrupled,

So it becomes 4a^2

So side is 2a

Thus perimeter = 2a*4=8a which is twice of initial perimeter.

So it becomes double.
