perimeter of a rectangle = 2 ( l + b )
= 2 ( 12 + 6 )
= 2 ( 18 )

Answer:-
Given,
Length of the rectangle is twice it's breadth that even means half of the length is breadth.
Length = 12cm [given]
According to the statement , breadth of the rectangle = 12/2 = 6cm
Perimeter of the rectangle = 2(l+b)
= 2(12+6)
=2(18)
=36cm
Therefore perimeter of the rectangle = 36cm.
