Answer 2

Hi bro you have said the total but you didn't said length and breadth

so if we take length is 200 cm

breadth is 40 cm

so length decreased 10. per so 200 is 190 and

breadth is increased 20. per so 40 is 60 so bro the perimeter of the total boundary is 45,000

I think it helps to you if any thing worng sorry for that I am a 5 th class student

Thank you
