128 square cm
Step-by-step explanation:
Perimeter of the Rectangle = 2(l+b)
length is twice the breadth
Let the Breadth = x
so, Length = 2x
Perimeter of Rectangle = 2(l+b)
48=2(x+2x)
48÷2 = x+2x
24=3x
24÷3=x
8=x
Therefore x=8
Breadth = x = 8cm
Length = 2x=2×8=16cm
Area Of rectangle = l×b
=8×16
=128 square cm
