Answer:

22s - 9

Step-by-step explanation:

The perimeter (P) is the sum of the 4 sides , that is

P = 2s + 7 + 9s - 5 + 6s - 10 + 5s - 1 ( collect like terms )

  = (2s + 9s + 6s + 5s) + (7 - 5 - 10 - 1)

  = 22s + (- 9)

 = 22s - 9

Answer:

22s - 9 is the perimeter

Step-by-step explanation:

Perimeter of the quadrilateral

= Sum of all sides (AB+BC+CD+DA)

= (6s-10)+(9s-5)+(5s-1)+(2s+7)

= 6s-10+9s-5+5s-1+2s+7

= (6s+9s+5s+2s) + (7-10-5-1)

= (22s) + (-9)

= 22s-9
