Answer 1

Answer:

the value of b will be given in your question replace it with the last part of the explanation, you will get the answer of the perimeter of the rectangle.

Step-by-step explanation:

let the length be l.

let the breadth be b.

given, l = 3b

perimeter of a rectangle, P = 2(l+b)

therefore, P = 2(3b+b)

therefore, P = 2(4b)

therefore, P = 8b
