Answer:
Length of the Rectangle = 12 CM
Step-by-step explanation:
Let the Length be L
Breadth = B
Its Given that
L = 2B
Perimeter of Rectangle = 2(L + B) = 36 CM
ie 36 = 2(L + B)
ie 36 = 2(2B + B)
ie 36 = 2(3B)
ie 36 = 6B
Therefore B = 36/6 = 6 CM
There fore Length = 2B = 2 X 6 = 12 CM

Answer:
12cm
Step-by-step explanation:
length of rectangle be l
and breadth be b
Perimeter of a rectangle = 2(l+b)
Perimeter=36cm
36=2(l+b)
l+b = 18 --------(1)
it is given that l=2b
so,
putting l=2b in (1)
2b+b= 18
3b=18
b=6cm
l=12cm
Length = 12cm
