Rod, A which is 30 cm long, expands by 0.045 cm when heated from 0oC to 100oC. Rod B, also 30 cm long expands by 0.075 cm for the same change in temperature. A third Rod C, also 30 cm long is made up of the materials of rod A and B, connected end to end. It expands by 0.065 cm when heated from 0oC to 100oC. Calculate the initial lengths of rods A and B in rod C.
