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

Answer:

Length= 24

Breadth= 12

Step-by-step explanation:

Perimeter of rectangle=2(length+breadth)

Here it is given that length(L) is twice of breadth(B)

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}

Now,

2(2B+B)=72

2(3B)=72

6B=72

B=72/6

B=12

Therefore Length= 2×12=24

Answer 2

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
