Answer: 120 cm².
Step-by-step explanation:
1. To solve this problem you must apply the formula for calculate the area of a triangle, which is:

Where <em>b</em> is the base and <em>h</em> is the height of the triangle.
2. Then, when you substitute the values given in the problem you obtain:

3. You know that the shape is made of 12 right triangle of equal size, therefore, multiply the area obtained by 12.
4. Then the area of the shape is:

Answer:
n = 2
Step-by-step explanation:
Given
(n - 4) - 3 = 3 - (2n + 3)
Multiply through by 2 to clear the fraction
n - 4 - 6 = 6 - 2(2n + 3) ← distribute
n - 10 = 6 - 4n - 6 ( add 4n to both sides )
5n - 10 = 0 ( add 10 to both sides )
5n = 10 ( divide both sides by 5 )
n = 2
4 can hold 8 gallons = 8/4 = 2 big bottle per gallons.
For 10 big bottles = 10 x 2 = 20 gallons.
If you are looking for how many bottles can be filled with 10 gallons, the answer is 5.
