Can someone plsss with 27 , 28,29!

The area for 27 is 64cm^2.

For the mean, you add up all the numbers then divide by how many numbers there are. So you would do 45+96+100+39+50 and divide it by 5. So your mean is 66.

Now for 29.
For when n=5 is 8
For when n=8 is 14
For when n=14 is 26

Hope this helps!

29
2(5)-2= 8
2(8)-2= 14
2(14)-2= 24

hope it is correct if not i'm srry i tried to
