a frame in the shape of trapezium ABCD is form by bending a thin uniform wire given that AB = 8cm AD = 6cm CD = 16cm, AB is parrellel to DC and BAD angle = 90*. Find the distance of center of mass of the frame from AD and AB

We don't provide homework answers - you must show us your attempt at solving this, and then we will help you along if you get stuck. But I'll give a hint to get you started: have you determined the length of BC yet? It helps to draw a diagram!
