Answer 1

Answer:

The answer to your question is Area = 62.5 u²

Step-by-step explanation:

Area = $c \frac{a + b}{2}$

a and b are bases

c = heigth

dAD = $\sqrt{(x2 - x1)^{2} - (y2 - y1)^{2} }$

dAD = $\sqrt{(-1 + 13)^{2} - (5 + 11)^{2} }$

dAD = $\sqrt{(12)^{2} - (16)^{2} }$

dAD = $\sqrt{144 + 256}$

dAD = $\sqrt{400}$

dAD = 20 u

dBC = $\sqrt{(3 - 0)^{2} - (2 + 2)^{2} }$

dBC = $\sqrt{9 + 16}$

dBC = $\sqrt{25}$

dBC = 5 u

dAB = $\sqrt{(3 + 1)^{2} - (2 - 5)^{2} }$

dAB = $\sqrt{(4)^{2} - (-3)^{2} }$

dAB = $\sqrt{16 + 9}$

dAB = $\sqrt{25}$

dAB = 5u

Area = $5 \frac{20 + 5}{2}$

Area = $5 \frac{25}{2}$

Area = 5(12.5)

Area = 62.5 u²
