Answer: She is not correct, because she must multiply the base and the height of the triangle and then divide by 2.
Step-by-step explanation:
1. The formula for calculate the area of a triangle is shown below:
Where 
is the base and 
is the height.
2. Then, if she applied the method she reasoned, she'd obtain the following area:
3. But actually, Magda should multiply the base and the height of the triangle and then divide by 2. Then, the correct area is:
Just remember: If a function is continuous at every value in an interval, then we say that the function is continuous in that interval. And if a function is continuous in any interval, then it is a continuous function. Thus, as long as there is no break in a graph or a line the function is continuous.
