Question 20

Identify the area of the polygon with vertices B (3, 2), C (7,-2), D (2,-4), and E (1, -2).
A = 19 units2
A = 17 units2
A = 30 units
A = 18 units2

Answer 1

Answer: A=18units2

Explanation:

I said 17 before and got it wrong lol.

Next time I said 18 cuz it seemed like the closest when I estimated what it looked like the units it covered, so it's right:)

hope it helps!

Answer 2

9514 1404 393

Answer:

(d) A = 18 units²

Explanation:

Line CE can be considered to be the base of two triangles. It is 6 units long. The upper triangle is 4 units high, and the lower triangle is 2 units high. The formula for the area of a triangle is ...

A = 1/2bh

Then the sum of the areas of the two triangles is ...

A = 1/2(6)(4) +1/2(6)(2) = 12 +6 = 18

The area of the polygon is 18 square units.
