give answer.......................,.,,,,........​

Answer 1

Step-by-step explanation:

let breadth be x

so length is 2x

length is incresed 20%=2x+20/100×2x

12x/5

breadth decreased by 20%=x-20%x

=4x/5

current perimeter =2(2x+x)=6x

new perimetr=2(12x/5+4x/5)=32x/5

so the perimeter has increased

so incrs%=32x/5-6x/6x×100

2x/5/6x×100

6.66%
