heya frnd!
here's ur answer...
let the breadth of the rectangle be x therefore the length will be 5+x.
perimeter of the rectangle=40cm
2(l+b)=40cm
2(5+x+x)=40cm
2×(5+2x)=40cm
10+4x=40-10
4x=30
x=30/4
x=7.5
hence, breadth of the rectangle=x
=7.5cm
length of the rectangle=5+x
=5+7.5
=12.5cm
verification:-
perimeter=2(l+b)
=2(12.5+7.5)
=2×20
=40cm
hence verified
hope this helps u...
