we know that perimeter of rectangle is 2(l+b)=190
so 2(l+b)=190
it is also given that difference between them is 15
2(l+b)=190
l+b=190/2=95
l+b=95
b=95-l
let length = x
breadth= 95-x
we know that difference between them is 15
x-(95-x)=15
x-95+x=15
x+x=15+95
2x=110
x=110/2=55
terefore length =55
breadth = 95-x = 95-55=40
so 2(l+b)=190
