at first,

area of breakfast area,

[tex] = {10}^{2} [/tex]

[tex] = 100 {ft}^{2} [/tex]

area of kitchen,

[tex] = 10 \times 14[/tex]

[tex] = 140 {ft}^{2} [/tex]

now, total area,

[tex] = 100 + 140[/tex]

[tex] = 240 {ft}^{2} [/tex]

rate per square ft = $ 1.29

total cost ,

[tex] = 240 \times 1.29[/tex]

= $ 309.60

answer is B.
