The centre of gravity of the trapezium as shown in below figure from the side is at a distance of

(h/3) × [(b + 2a)/(b + a)]

(h/2) × [(2b + a)/(b + a)]

(h/3) × [(2b + a)/(b + a)]

(h/2) × [(b + 2a)/(b + a)]

(h/3) × [(b + 2a)/(b + a)]

(h/2) × [(2b + a)/(b + a)]

(h/3) × [(2b + a)/(b + a)]

(h/2) × [(b + 2a)/(b + a)]
