Breadth of a bedroom= 15 feet

Height of a bedroom= 8 feet

Area of walls of a bedroom= 2(l+b)×h

Area of walls of a bedroom=2(20+15)×8 $ft^{2}$

Area of walls of a bedroom= 2× 35×8 $ft^{2}$

Area of walls of a bedroom=560 $ft^{2}$

Amount of paint in 1 gallon = 400 $ft^{2}$

Number of gallons required= $\frac{560}{400}$

Number of gallons required= 1.4 gallons
