Answer 1

We are given dimension of billboard as 30 feet by 18ft.

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

so for 540 square feet paint needed = 540/250 = 2.16 gallons

Answer: 2.16 gallons should be purchased to cover the entire billboard
