Answer:
   x = -9
Step-by-step explanation:
Segment NL is twice the length of midsegment WV.
   2WV = NL
   2(x+15) = x+21
   2x +30 = x +21 . . . . simplify
   x = -9 . . . . . . . . . . . . add -30-x

<em>Additional comment</em>
This value of x means the other segments are ...
   MN = 12
   WV = 6
   NL = 12

Answer:
The perimeter is 22.
Step-by-step explanation:
If you turn this shape into a rectangle, the perimeter doesn't change.
The width is given, it is 7.5. The height is BC+DE = 3.5
Then the perimeter is twice the width plus twice the height:
7.5*2 + 3.5*2 = 15+7 = 22
 
        
             
        
        
        
Hi 
I belive you add the top side (4) plus the bottom side (9.5) witch would equal 13.5 times the hieght (3) equals 40.5 divided by 2 equals 20.25. the area is 20.25ft squared
another way to do it
4+9.5= 13.5 
13.5×3= 40.5 
40.5÷2= 20.25ft
