Question

length of a rectangular field is 6 times its breadth. if the length of the field is 120m. find its breadth and perimeter of the field? ​

Answer 1

Answer:

20 . 280

Step-by-step explanation:

Let the lenght be 6x

Let the lenght be 6xLet the breadth be x

6x=120

x=120/6

x= 20

Breadth = 20m

Perimeter = 2*(l+b)

2*(120+20)

= 2*140

280m

Answer 2

Solution :-

Let the breadth be x.

ATQ,

$\pink{\tt{ \mapsto x = \dfrac{\cancel{120}}{\cancel{6}} }}$

$\blue{\tt{ \mapsto x = 20 }}$

Hence, breadth is 20m.

$\purple{\sf{ Perimeter = 2 × (120m + 20m) }}$

$\orange{\sf{ \quad \quad \quad \quad \; = 2 × 140m }}$

$\green{\sf{ \quad \quad \quad \quad \; = 280m }}$

Hence, perimeter of the rectangular field is 280m.
