LOTS OF POINTS ANSWER ASA P , painter is painting a rectangular wall that measures 25.1 ft by 18.5 ft. Each gallon can of paint
svlad2 [7]

Answer:

1.548 gallons

Step-by-step explanation:

Length of the rectangular wall = 25.1 ft.

Width of the rectangular wall = 18.5 ft.

Area of the rectangular wall = length * width = 25.1 * 18.5

= 464.35 square feet

300 square feet wall can be painted using 1 gallon of paint.

=> 1 square feet wall can be painted using \[\frac{1}{300}\] gallon of paint.

=> 464.35 square feet wall can be painted using \[\frac{1}{300} * 464.35\] gallon of paint.

= 1.548 gallons of paint
