Question

Length and breadth of a rectangle are in the ratio of 5:3. If the perimeter of rectangle is 48 cm,
length and breadth of rectangle.​

Answer 1

Step-by-step explanation:

perimeter = 48

ratio of length into breadth of rectangle = 5:3

let the length of the rectangle be 5x

let the breadth of the rectangle be 3x

perimeter of a rectangle = twice of length plus breadth

48 = 2 into 5 x + 3 x

48 = 2 into 8 x

48 = 16 x

x = 48/16

x = 3

therefore the length of a rectangle = 5 x = 5*3=15

the breadth of a rectangle = 3 x = 3*3= 9

Answer 2

$\huge\bold\red{Answer}$

Let the ratio of length and breadth be x.

Then,

• Length = 5x
• Breadth = 3x

⇒Given,

Perimeter of rectangle = 48cm.

⇒Now,

We know that,

$perimeter \: of \: rectangle = 2(length + breadth)$

➪According To Question,

$2(l + b) = 48cm \\ 2(5x + 3x) = 48cm \\ 10x + 6x = 48cm \\ 16x = 48cm \\ x = \frac{48}{16} cm \\ x = 3$

Hence,

Length of rectangle=> 5x = 5(3) = 15cm.

And

Breadth of rectangle => 3x = 3(3) = 9cm.
