Question

The length of a rectangle is twice of its breadth. If its perimeter is 48 cm, find the dimensions
of the rectangle?
od 14 cm. The perimeter of the triangle is 36 cm. What​

Answer 1

Answer:

Dimensions -:

Length = 16 cm

Breadth = 8 cm

Step-by-step explanation:

Given :

Length is twice than Breadth

Perimeter = 48 cm

To find :

Their dimensions

Concept :

Let the Breadth be x

Let the Length be 2x

Using the perimeter formula to find the dimensions of the rectangle -:

$\boxed{\sf{2(2x+x)=48cm}}$

After we will get the value of x that will be the Breadth . And after that to find the length just do twice of it .

Solution :

$:\implies\sf{2(2x+x)=48cm}$

$:\implies\sf{4x+2x=48cm}$

$:\implies\sf{6x=48cm}$

$:\implies\sf{x=\dfrac{\cancel{48}cm}{\cancel{6}}}$

$:\implies\sf{x=8cm}$

So , the Breadth is 8 cm .

Length -:

$:\implies\sf{8cm\times2}$

$:\implies\sf{16cm}$

So , the length is 16 cm .
