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.)
