1. A thin brass sheet at 15 ˙C has the 20.023 Sq.cm. surface area while thin steel at 20˙C of 20 sq.cm. At what temperature the two sheets have the same area.

The "area expansion" part of the Wikipedia page should be what you need; you just need to look up the thermal expansion coefficient for brass and steel to use the equations there. https://en.wikipedia.org/wiki/Thermal_expansion
