Sagot :

The area to be covered by the paint = 875 sq ft.

Number of gallons used = 7 gallons.

Area covered by 1 gallon is calculated as,

[tex]\begin{gathered} Area\text{ covered by 1 gallon = }\frac{875}{7} \\ Area\text{ covered by 1 gallon = 125 sq ft} \end{gathered}[/tex]

Area covered by 35 gallons is calculated as,

[tex]\begin{gathered} Area\text{ covered by 35 gallons = 35 }\times\text{ 125 sq ft.} \\ Area\text{ covered by 35 gallons = 4375 sq ft.} \end{gathered}[/tex]

Thus area covered by 35 gallons is 4375 sq ft.
