Question

The length of a rectangle in twice its breadth . If the perimeter is 72 meters , find the length and breadth of the rectangle​

Answer 1

If the perimeter is 72 m .

Let the breadth of rectangle be x & the length of rectangle be 2x respectively.

Thus,

The length of rectangle will be 2 × 12 = 24 m

Answer 2

Step-by-step explanation:

Perimeter of recatngle = 2(length+breadth)

Here it is given that length is twice of breadth

Let 'L' be the length and 'b' be the breadth then

It is given that L=2b

And as per given information

2(L+b)=72

We can replace 'L' with '2b' because it's twice of b

Then we will get

2(2b+b)=72

2(3b)=72

6b=72

b=72/6=12

Therefore Length= 2×12=24
