Question

The length of a rectangular field is double its breadth.If the perimeter of the field is 60m,Find the breadth of the field.the answer in option 30m,5m,20m,10m is 10m.
How its possible explain...​

Answer 1

Step-by-step explanation:

Let the breadth (b) of the rectangular field be x

∴length(l)=2x

As we know that, perimeter of rectangle (P) is given as-

P=2(l+b)

⇒P=2(2x+x)

⇒P=2(3x)

⇒P=6x

Given that perimeter (P) of the rectangular field is 60m

∴6x=60

⇒x=

6

60

=10m

Therefore,

Breadt of the field =10m

Length of the field =2×10=20m

Answer 2

Answer:

Step-by-step explanation:

let the breadth of the field be x m

length = 2x (according to Question)

2( l + b) = 60

2(2x + x) = 60

2(3x) = 60

6x = 60

x = 10 m

so the breadth is 10 m.
