PLEASE SELECT MY ANSWER AS THE BRAINLIEST ANSWER.

Answer 2

LET THE LENGTH OF OLD RECTANGLE BE x .
LET THE BREADTH OF OLD RECTANGLE BE y .

NOW THE LENGTH AND BREADTH BOTH IS DOUBLED OF THE LENGTH AND BREADTH GIVEN IN OLD RECTANGLE.

SO THE LENGTH OF THE NEW RECTANGLE IS 2x .
BREADTH OF NEW RECTANGLE IS 2y .

SO PERIMETER OF OLD RECTANGLE = 2(l + b)
= 2(x + y) ........ (1)
NOW PERIMETER OF NEW RECTANGLE
= 2(2x + 2y) ........ (2)

NOW DIVIDE (2) BY (1) , WE GET

= 2(2x + 2y)
_________

2(x + y)

SO THERE WILL BE 2 LEFT AFTER DIVIDING THIS.

SO YOUR ANSWER IS THE PERIMETER IS INCREASED BY TWO TIMES THAT OF OLD RECTANGLE TO THE NEW RECTANGLE.



HOPE THIS ANSWER HELPS YOU!!!!!
