Question 1199580
<br>
From your description, I'm not sure what you/we are supposed to do with this....<br>
Segments AB, AC, and AD are all vertical, and segments CE, BF, and AG are all horizontal, so our three triangles DCE, DBF, and DAG are all right triangles; the area of each is easily found using the formula Area = one-half base times height, where in each case the base and height are the two legs of the right triangle.<br>
So that part should be straightforward.<br>
But then you talk about the area under "the curve"; but there is no curve in the problem.<br>
Points D, E, F, and G all lie on the same straight line; if segment DG is "the curve", then the area under "the curve" is the area of triangle DAG.<br>
If in fact "the curve" is a continuous curve that passes through points D, E, F, and G, but not in a straight line, then the area under "the curve" is APPROXIMATELY the area of triangle DAG.<br>
If this response doesn't answer the question(s) you have, re-post the problem, making it more clear exactly what the problem is.<br>
