Question 1111013
let width be 		x									
length will be 		2	x								
Area of rectangle = 		2x^2									
both dimensions are increased by 4											
											
width =	x	+	4								
											
length =	2	x	+	4							
											
As per the condition											
											
(x+	4	)*(	2	x+	4	)=	2	x^2+	88	)	
											
2	x^2+	4	x+	8	x	16	=	2	x^2+	88	
											
Simplify											
											
12	x=	72									
	x=	6									
											
width = 	6	m									
											
length=	12	m
