Find the area of the polygon with the given vertices. N(-2,1), P(3,1), Q(3,-1) R(-2,-1)

Question

I need help whats the answer?

Answer 1

This polygon is a rectangle at 3-(-2)*1-(-1)=10sq.

Answer 2

Well, we could use the formula to find the distance between your points, but hopefully you can see that you have a rectangle with verticle and horizontal sides.

What's the distance between (-2,1) and (3,1). They are across from each other, so they are |3 - (-2)| = 5 apart. Q and R are the same.

P is directly above Q, so the distance is |1 - (-1)| = 2 . Same for N snd R.

5(2) = your answer
