Arectangle billboard is 30 feet by 18 ft. if a gallon of paint cover 250 square feet how many gallons should be purchase to cover the entire billboard

since billboard is a rectangle so Area =l *b

Area of billboard = 30*18=540 feet square

1 gallon of paint covers 250 square feet

2.16 gallons should be purchased to cover the entire billboard
