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:
The graph is attached, showing the intersection point at 13.5 years and populations of 235.2 for each population.
We only consider the portion of the graph from x=0 on, since negative time is illogical. Tracing the graph we get the intersection point.
