Question

the length of the rectangular field is twice its breadth the perimeter of the field is 60 M find the length and breadth of the field

Answer 1

HEYA!
--------

Let the breadth be x

Then length becomes 2x

$perimeter = 2(l + b)$


$= > 2(x + 2x) = 2 \times 3x \\ \\ = 6x$
Given perimeter = 60 m

Therefore

6x = 60

X= 10


hence the breadth is 10 and length is 20m

Answer 2

let the breadth of rectangle be x
and length be 2x
Perimeter of rectangle
2(l+b)
2(2x+x)=60
4x+2x=60
6x=60
x=60÷6
x=10
now,the value of x is 10
y= 2× 10
y= 20
length= 20
breadth= 10
