Question

#The length and breadth of a Rectangle is 80 m and 40m respectively.If the length is increased by 5% and breadth is decreased by 5% than what will be the diffrence in perimeter?​

Answer 1

Answer:

Length(l)=80m

Breadth(b)=40m

Perimeter(P)=2(l+b)

2*(80+40)=240m

Now,

length(l1)=80+5%*240=92m

breadth(b)=40-5%*240=28m

Perimeter(P1)=2(l+b)

=2*(92+28)

=240m

There is no difference in perimeter.
