The perimeter of a rectangle is twice the sum of its length and its width the perimeter is 28 m and it's length is 2 m more than twice its width what is its length

Hello : 
x : length     y : width
2(x+y) = 28(1)
x= 2y+2(2)
subsct in : (1)
2(2y+2+y) =28
3y+2=14
 3y=12
y= 4 m
x= 2(4)+2 = 10 m

You need to show the box plots
