Answer:
let the breadth of the rectangle be x
therefore the length will be 2x
The perimeter of a rectangle = 2(l +b)
According to the question ,
the area of the rectangle = l×b = 288cm square
so, X × 2X= 288
X = √144
X = 12
the length = 12x 2cm=24cm
the breadth = 12cm
2(l+b)= 2( X+2X)cm
2(12 + 24)cm
72cm
therefore the perimeter of the given rectangle is 72cm
