a) Area = l x w = 24ft x 45ft = 1080 $ft^{2}$ Insurance value = 1080 $ft^{2}$x 110 = 118,800 b) Area of the upper rectangle = l x w =24 ft x 85 ft = 2040 $ft^{2}$ Area of lower rectangle = lxw = 19ft x 16ft =304 $ft^{2}$ Total Area = 2040 + 304 = 2344 $ft^{2}$ Insurance value = 2344 x 110 = 257,840
