The rectangular plate shown if Fig. 1.7 has an area A_i . If the temperature increases by DeltaT , each dimension increases according to DeltaL=alphaLDeltaT , where alpha is the average coefficient of linear expansion. Show that the increase in area is DeltaA=2alphaA_iDeltaT . What approzimation does this expansion assume?

Unit of coefficient of linear expansion
