So here is your answer..
solution:-
we know that :area of square =a×a =a² sq. unit
case 1st;
if it's length of side halves ,then
side of square =a/2
and area of square =(a/2)²= a²/4
it means when we halve the length then are become one by 4th times of area .
case 2nd;
if the length of side double, then
side =2a
area of square =(2a) ²=4a²
it means area become 4 times if it's side is doubled.
