Area of wall is 8.75 x 11.25 = 98.4375 square feet. So 200 foot coverage should be easy to do.
Two coats = 2 x 98.475 = less than 200 so two coats can be applied.
Be careful with the number of significant digits. I am assuming these are EXACT numbers; therefore, I included all of the digits.

(A.) Area = length*width
(B.) See if you have enough paint to cover twice that area. (The amount of paint you have should be more than twice the area of the wall.)

A. 98 7/16ft^2 b. Yes. Two coats will take enough paint for 2*98 7/16 = 196 7/8 square feet, which is less than the 200 square feet the paint should cover
