Question

What is the area of the triangle in the diagram?

Answer 1

12(x1−y1)(x2−y1)

12y1(x2−x1)

12(x2−x1)

12(x22−y21)(x21−y21)

Answer 2

Is there a picture?

Answer 3

hold on for on moment

Answer 4

do u see it

Answer 5

Yeah, I'm just a little stuck :/ I kinda forgot how to do this tbh

Answer 6

thats ok just help me the best u can

Answer 7

Well I know that if you multiplied 7 and 3 (the length and height) and divided by 2 would give you 10.5, but it doesn't give you multiple choice answers in that format...

Answer 8

Otherwise I would've thought that'd be the answer. The numbers following the variables are exponents right?

Answer 9

the area of a triangle = 1/2 * base * perpendicular height
the height would be y1 and the base (x2 -x1)

Answer 10

x1 is negative so it becomes
1/2 (x2 + x1) * y1

Answer 11

for any x1 so option B would be correct

Answer 12

any questions ?
