Ok, so I'm pretty sure this one is 11.5 I just wanted to make sure with u guys! :)

C: 23 cm

Step-by-step explanation:

This is the answer because:

1) Area of trapezoid is: (base1 + base2)/2 x height

2) In this case, it is 14 + 8 which is 22. 22/2 is 11.

3) Now we have to do 253/11 which is 23 cm.

Hope this helps! :D
