Question

length and breadth of rectangle are in a ratio of 3: 5 and thier perimeter os 140 m find length and breadth​

Answer 1

Answer:

let's the length is 3x and breadth be 5x

now according to question

perimeter of rectangle= 2(l+b)

=>2(l+b)=140

=>2(3x+5x)=140

=>16x=140

=>x=140/16

=>l=140/16×3

=>b=140/16x5
