Explanation

The premises of showroom which are to be renovated are: Reception area, General Manager's room, pantry, service desk and display area. So, total area of the above rooms = Area of (reception + General Manager's room + pantry + service desk + display area) = 1287 sq. m + 621 sq. m + 1368 sq. m + 713 sq. m + 1209 sq. m = 5198 sq. m. But the total area of the car showroom is 6000 sq. m. So, area which is not to be renovated = Total area of the car showroom - total area of the rooms to be renovated = 6000 sq. m - 5198 sq. m = 802 sq. m. Therefore, the percentage area of the showroom not to be renovated = 802 sq. m/6000 sq. m x 100 = 13.36%
