Answer:

11. X=7

For 12, im not sure but I think it's

Step-by-step explanation:so for 11 I just divided 70 by 10 cuz to find the area of a rectangle or square you multiply the width by length. For 12 I think it's 5 because I know that you multiply the width by length then divide it in half.

Also what grade are you in?
The answer is 7 it’s exactly what the other girls said also sorry if I’m late but yes the other girls is correct
