Homework Statement
an isosceles triangle with mass m and constant density is placed on an xy plane with base on the y axis. its height ranges from (0,-b/2) to (0,b/2) and its height is (a,0)
Find its center of mass.
I know that its density is equal 2m/ab.
The Attempt at a Solution
The solution says that the shape of the small strips which i am supposed to integrate from zero to a are given by 2*b/2a*(a-x)
What I don't understand is why the heght b/2 is divided by a? I would appreciate it if someone could explain this to me. Thanks
