IMATLAB problems. Please need help solving these two questions. Can you PLEASE show MATLAB code.

Thank you

Give a box below, its volume l-. Use Lagrange's multiplier method, find its dimensions, a, b and/ so that its surface will be minimized The figure shows a two-spring system before and after loads are applied at joint. We shall determine the equilibrium state of the loaded system that is, the location (xl, x2) oftheint. This can be achieved by minimizing the potential energy (PE) with respect to the design variables and to obtain the new location of joint. F2 4.5 N 88 N/em 11 cm F 45 N The potential energy is computed from the difference between the strain energies of the springs, which is given by the first two terms in the equation, and the work done by extemal forces, which is given by thoe last two terms in the Eq - A2.1.1 Nem -11 cm Use fiminsearch to find the locations of the minimum PE
