Letty, I understand that you have a lot of homework in front of you.
If you have difficulties doing the homework, it means that you will need to catch up with the material. Someone else doing the homework for you does not make your next homework easier!

Wow!
you really expect somebody to do an assignment of 36 questions for you ??

you attempted only 2 of these (#13 and #31 you got #31 correct)

also #19 and #24 make no sense

actually #13 does not make aney sense either.
you said:
13. The width of a rectangle is fixed at 12cm. What lengths will make the perimeter 72cm.
The length must be greater than ----- cm. Is it 48

let the length be l
then 2l + 2(12) = 72
2l = 72 - 24
2l = 48
l = 24

if l > 24 then the perimeter > 72
but you want the perimeter to be equal to 72, so the length has to be equal to 24.
Where does the "greater than" come in ?
