Answer:
A=150
Step-by-step explanation:
you can split the shape into a square and triangle. the square's area is 15 x 6 = 90. the triangles area is (1/2) (14-6) (15)= 60. then you add them together and get 150
1 gallon = 16 cups
1 quart = 4 cups
1 pint = 2 cups
Therefore...
Multiply
5 gallons × 16 cups = 80 cups
12 quarts × 4 cups = 48 cups
7 pints × 2 cups = 14 cups
Then...
Addition
80 cups + 48 cups + 14 cups = 142 cups
