Answer:
Length = 16cm.
Breadth = 8cm
Step-by-step explanation:
Let us assume that the breadth of the rectangle is x.
It is given that length is twice the breadth, thus 2x.
Perimeter = 2 ( l+b)
Substituting the values given, we get :-
48 cm = 2 ( 2x+x)
48 = 2 * 3x
48/2 = 3x
24 = 3x
x = 24/3
x = 8cm
We have found the breadth now. Length is twice the breadth.
Length = 8 * 2
Length = 16cm
Breadth = 8cm

Answer: The answer and explanation will be below.
Step-by-step explanation:
Perimeter of rectangle=2(l+b)
48=2(l+b)
48/2=(l+b)
24=(l+2b)
24/2=(l+b)
6=b
L=2b
L=2xB
L=2x6
L=12
So,Length is 12 and breadth is 6
