Question

The length of a rectangular field is 6 times its breadth. If the length of the field is 120 cm, find the breath and perimeter of the field
​

Answer 1

Step-by-step explanation:

Let breadth be x then,

length= 6x=120 cm

x=120/6

x=20

therefore length = 20

so, perimeter of rectangular field = 2(l+b)

=2(120+20)

=2(140)

=280 cm

Answer 2

Answer:

Given :

$\textsf{Length of the rectangular field = 120 cm}$

$\textsf{Breadth is 6 times of its length }$

To find :

$\textsf{(i) Breadth}$

$\textsf{(ii) Perimeter}$

Concept :

Let the Breadth be x

To find the perimeter of the rectangular field . First find the Breadth of the rectangular field.

To find divide the length with 6 .

$\sf{6x=120cm}$

$\sf{x=\dfrac{120cm}{6}}$

$\sf{x=20cm}$

So , the Breadth of the rectangular field is 20 cm . To find the perimeter of the rectangular field use this formula.

$\sf{\boxed{P=2(L+B)}}$

Solution :

$\sf{\implies{P=2(120cm+20cm)}}$

$\sf{\implies{P=2\times140cm}}$

$\sf{\implies{P=280cm}}$

Answer :

So , the breadth of the rectangular field is 20 cm .

And the perimeter of the rectangular field is 280 cm .
