1. A department store plans to construct a one-story building with a rectangular planform. The building is required to have a floor area of 22,500 ft? and a height of 18 ft. It is proposed to use brick walls on three sides and a glass wall on the fourth side. Use the Lagrange multipliers to find the dimensions of the building to minimize the heat loss, assuming that the relative heat losses per unit surface area for the roof, brick wall, glass wall, and floor are in the proportion 4:2:5:1

Transcribed Image Text:1. A department store plans to construct a one-story building with a rectangular
planform. The building is required to have a floor area of 22,500 ft? and a height of
18 ft. It is proposed to use brick walls on three sides and a glass wall on the fourth
side. Use the Lagrange multipliers to find the dimensions of the building to minimize
the heat loss, assuming that the relative heat losses per unit surface area for the
roof, brick wall, glass wall, and floor are in the proportion 4:2:5:1
