Question

The twice it's breadth.If the parameter is 72meter.Find the length and the breadth of the rectangle

Answer 1

Answer:

B = 12

L = 24

Step-by-step explanation:

Let the breadth  be x

so, the length is 2x

Perimetre of rect  = 2(l+b)

72 = 2(2x + x )

72 = 2 ( 3x)

72 = 6x

$\frac{72}{6}$ = x

12 = x

Breadth = x = 12

Lenght = 2x = 12 *2 = 24

Answer 2

Answer:

Length = 24 m  and Breadth = 12 m.

Step-by-step explanation:

Let breadth be  x m

Now length is twice as given in question .

Length = 2 x

Also perimeter is given 72 m.

We know formula for perimeter of rectangle.

Perimeter = 2 ( l + b )  

Now putting values here we get

2 ( 2 x + x ) = 72

( 2 x + x ) = 36

3 x = 36

x = 12.

So for breadth = 12 m and length = 2 × 12 = 24 m .

Verification :

Put values of length and breadth in perimeter's formula

Perimeter = 72 m

2 ( 12 + 24 )

2 ( 36 )

72 m

Hence verified.
