Alexei wants to hang a mirror in his boat but the mirror and frame must not have an area larger than 19.25 square feet. The mirror is 3 feet wide and 5 feet long. Which quadratic equation represents the area of the mirror and frame combined? (The border must have equal width on each side.)

A. 2x^2 + 8x − 19.25 = 0
B. 3x^2 + 5x − 19.25 = 0
C. 4x^2 + 16x − 4.25 = 0
D. 4x^2 + 16x + 15 = 0

I believe the answer is C? Is that right?
