let breadth be x m
then length Will be 2x
ATQ:
2( l + b ) = 60
2(x + 2x) = 60
2 × 3x = 60
6x = 60
x = 10
length = 2x = 2 × 10 = 20 metres
then length Will be 2x

ans please

Breadth is equal to 'x'
Length is equal to '2x'
Perimeter=2(l+b)
=2(x+2x)
=6x
6x=60
x=60/6
x=10
Therefore, Breadth=x=10
Length=2x=2*10=20
