Answer:
b=12
Step-by-step explanation:3b-6=a,ab=360,b=?
(3b-6)b=360
3b^2-6b=360
b^2-2b=120
(b-1)^2=121
b-1=11
b=11+1=12

Let the breadth of the rectangular field is x m.
According to the given condition,
the length is [ 3x-6] m.
area of the rectangular field =360m sq
= length × breadth
=[3x-6]× x
=3x²-6x =360
=3x²-6x-360=0
=x²-2x-60 =0
And rest of this I think you can solve by yourself.
Solve this equation and get the answer by your own.
