The distance would be 21. to find the difference, add the absolute values so 12+9, which equals 21
Answer:
The area is 84. The missing side is 7.
Step-by-step explanation:
Okay so perimeter = length+length+width+width right? If 12 is the length, then 12+12=24, which is the length part of perimeter. 38-24=14 and 14/2=7. The missing side is 7 because 12+12+7+7=38 and the area is 84 because 12x7=84. Good luck!
