These are definitely corrects 100%, please tell me how to solve.

The channel shape cross-section and the rectangular cross-section shown in the Figure Q4 are made of materials with elastic-perfectly plastic behaviour. The yield stress of the material used for the channel shape cross-section is σy = 449 MPa, whereas that used for the rectangular cross- section is 0.7%y. Compute the thickness of the web, t, of the channel shape section if the two cross sections have identical plastic bending moment about the z-axis. In Figure 4, h= 96 mm, b=43 mm, a=12 mm, H=96 mm, d= 43 mm N b h a Z a | d H
