$252,360

#### Work Step by Step

Area of the upper rectangle = l x w
=28 ft x 75 ft = 2100 $ft^{2}$
Area of lower left rectangle = lxw
= 16ft x 26ft
=416 $ft^{2}$
Area of lower right rectangle = lxw
= 12ft x 24ft
=288 $ft^{2}$
Total Area = 2100 + 416+ 288 = 2804 $ft^{2}$
Insurance value = 2804 x 90 = 252,360
