Answer 1

Let b be the breadth of rectangular varanda

and length be l

According to the question,

@  l = 3 metre + b-----------equation 1

@ 2(l+b) = l×b

  2(3+b+b) = 3+b×b

  2(3+2b) = 3b+b^2

   6 + 4b = 3b + b^2

   b² + 3b - 4b -6 = 0

   b² -b -6 = 0

   b² -3b +2b -6 =0

   b(b-3) + 2(b-3) =0

   ( b+2 )  (b-3 ) =0

    b= -2     b= +3

        ∴ b=3 metre

From equation 1

l = 3+b

 = 3+3

∴l= 6 metre
