40 m A rectangular building covering 3,200 m is to be built on a lot as shown to the right. If the building is to be 50 m from the boundary on each side and 40 m from 50 m the boundary in front and back, find the dimensions of the building if the area of the lot is to be minimized. 3,200 m ly 50 m- X 140 m The dimensions are m. (Use a comma to separate answers as needed. Type integers or decimals rounded to one decimal place as needed.)
