Answer: He will need
$3\frac34$ gallons of paint to paint the entire wall.

Explanation:

Given : Area to paint = 142.5 square feet

Paint used to paint
$\frac15$ of the wall =
$\frac34$ gallon

Paint used to paint complete 1 wall =
$5*\frac34$ gallons

Paint used to paint complete 1 wall
=(15)/(4)=3(3)/(4) gallons

Hence, he will need
$3\frac34$ gallons of paint to paint the entire wall.
