Android Studio aligning elements to other elements under them

Hello I'm using android studio for mobile app development and I need to make 3 LinearLayouts the same size. The problem is that the first element contains different element. I need to stretch first element to have exactly the same size as others. I guess I can somehow get to know that is the size of elements and set the value to the first element. Maybe there is a possibility to align them somehow? That is how it looks. Thanks for help!
