Question

Find the perimeter of a rectangle if its length is three times of breadth

Answer 1

Answer:

8x

Step-by-step explanation:

Let the breadth be x metre

Length = 3x metre

Now , perimeter = 2(l+b)

= 2(x+3x)

= 2 × 4x

= 8x metre.

Answer 2

Explanation:-

Required answer:-

♣️ We know that, perimeter of the rectangle = 2(l+b)

♠️ Let's length = 3x

♠️ Let's breadth = x

Putting length value and breadth value.

Perimeter of the rectangle = 2(3x + x)

Perimeter of the rectangle = 2(4x)

Perimeter of the rectangle = 8x
