Im gonna asume you mean side, so 1 foot = 12 inches (:
0.45 * 2 is 0.9
$1.44 * 2 is $2.88
$1.44/9 is $0.16
$0.16 * 2 is $0.32
$2.88+$0.32 is $3.20
The answer is $3.20
Part 1: 4 quarts in a gallon
4 * 5 = 20 quarts
Part 2: 20 * 2 = 40
They will make $40.00
4 units wide would be the answer bc the deminsions of the legs wouldn't change for a rectangle or a triangle
