A thin brass sheet at 10°C and a thin steel sheet at 20°C have the same surface area. The common temperature at which both would have the same area is (Coefficient of linear expansion for brass and steel are respectively, $\left.19\times {10}^{-6}{/}^{\circ }\mathrm{C}\text{ are }11\times {10}^{-6}{/}^{\circ }\mathrm{C}\right)$
