A flat square of side s0 at temperature T0 expands by Îs in both length and width

Question:

A flat square of side s0 at temperature T0 expands by Δs in both length and width when the temperature increases by ΔT. The original area is s02 = A0 and the final area is (s0 + Δ s)2 = A. Show that if Δs
A flat square of side s0 at temperature T0 expands

(Although we derive this relation for a square plate, it applies to a flat area of any shape.)
