is in °C.The ambient temperature T, is 25°C, and the surface area A of the wall is 10 m?. If the heat transfer coefficient h is given as 20 W/m²°C,the heat transfer from the wall is given by ſ[T(t) – T, ]hA dt. Using the trapezoidal rule, compute this integral as accurately as possible for the time interval t = 6 to t = 12. Also evaluate the integral analytically and compare the result with the computed value. Use the quad function in MATLAB to verify the results obtained.-
