Answer:
The length is 13, when the width is 11
Step-by-step explanation:
The width is x, when the length is x+2. The area is x(x+2)= x^2+2x.
The perimeter is (x+x+2)*2= (2x+2)*2=4x+4
THe thrre times perimeter is 3(4x+4)= 12x+12
x^2+2x= 12x+12-1
x^2+2x-12x-11=0
x^2-10x-11=0
x=-1 (not suitable); x=11 - the width
The length is 11+2=13
