The figure PQRS is a parallelogram. Point M is the mid-point of PS.
What is the length of QY? 26 units 20 units 30 units 36 units
I think it may be 20?
On this one you cann look at the fact that QY is parallel to SR, but it's also bigger then SR. So you are right it is 20, but also it's half of it as well. So 10 +10=20. :) You was right.
You're welcome! :) Glad to help!!
