Calculate the area of triangle abc with altitude cd, given a (6, 0), b (1, 5), c (2, 0), and d (4, 2).

a. 5 square units
b. 8 square units
c. 10 square units
d. 13 square units

Check the picture below.









now, from the picture.. you can, without using AB and CD, see the base and see how many units on the grid, and see the altitude as well, and get the area that way, and you'd get the same.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
