Determine the area of a triangle with sides of the following length:
a = 19 m
b = 20 m
c = 21 m
a. 192 m2
c. 172 m2
b. 180 m2
d. 183 m 2

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.

(6,0) i hope it makes enough sense
