895 inches + 1 diameters = 915 inches
1 diameter = 915 -895 = 20 inches (radius = 10 inches)
The rectangle Diagonal = 1,000 -20 = 980 inches
(Left Side of the rectangle)^2 = 980^2 - 915^2
(Left Side of the rectangle)^2 = 960,400 -837,225
(Left Side of the rectangle)^2 = 123,175 inches
Rectangle Left Side = 350.9629610087 inches
Rectangle Area = 915 * 350.9629610087 = 321,131.11 square inches
Area of THREE circles = 3 * PI * 10^2
Area of THREE circles = 942.48 square inches
TOTAL AREA = 321,131.11 + 942.48 = 322,073.59 square inches
That's about as well as I could do.
