Question

the length of a rectangle is twice its breadth if its perimeter is 72m. find the length and breadth of the rectangle​

Answer 1

Answer :

• Length of rectangle = 24 m

• Breadth of rectangle = 12m

Given :

• The length of a rectangle is twice its breadth.

• Perimeter of rectangle = 72m

To Find :

• The length and breadth of the rectangle.

Step By Step Explanation :

We know that,

The length of the rectangle is twice it's breadth

and perimeter of rectangle = 72m.

We need to find the length and breadth.

Let us consider length be 2x and breadth be x.

So let's do it !!

As we know ⤵

$\dag\boxed{\bf{\green{Perimeter_{(Recatangle)} = 2(Length + Breadth)}}}$

$\bf \: By \: substituting \: the \: values \\ \\ : \implies\sf72 = 2 (2x + x) \\ \\ : \implies\sf72 = 4x + 2x \\ \\ : \implies\sf72 = 6x \\ \\ : \implies\sf\cancel\cfrac{72}{6} = x \\ \\ : \implies\bf 12 = x$

Therefore x = 12

Length = 2x => 24 m

Breadth = x => 12

Answer 2

Answer

: the length of a rectangle is twice its breadth. If the perimeter is 72 metre, find the length and breadth of the rectangle. 36m=3W Divide each side by 3. 12m=W ANSWER 1: The breadth is 12 meters.
