Answer: this is best answer
Step-by-step explanation:Let the breadth of a rectangle = x m.
Thrice its breadth=3x m
Length of a rectangle= 3x-6 m
Perimeter of a rectangle = 2(l+b)
=2(3x−6+x)
=2(4x−6)
=8x−12
But we are given perimeter=148 m
8x−12=148
8x=148+12
8x=160
x=20 metres
Breadth=x= 20 metres
and Length=3x−6=3×20−6=60−6=54 metres.
