Triangle GHI, with vertices G(-8,-8), H(-6,-7), and I(-9,-2),

Anna35 [415]

Answer:

area = 6.5 square units

Step-by-step explanation:

Use the <em>area of a triangle in coordinate geometry</em> formula:

$\triangle GHI =\frac{1}{2} |x_1(y_2- y_3) + x_2(y_3 -y_1) + x_3(y_1 -y_2)|$

where $(x_1,y_1)=(-8,-8) \ \ \ \ (x_2,y_2)=(-6,-7) \ \ \ \ (x_3,y_3)=(-9,-2)$

$\triangle GHI =\frac{1}{2} |x_1(y_2- y_3) + x_2(y_3 -y_1) + x_3(y_1 -y_2)|$

$\implies \triangle GHI =\frac{1}{2} |-8(-7+2) -6(-2 +8) -9(-8 +7)|$

$\implies \triangle GHI =\frac{1}{2} |40 -36 +9|$

$\implies \triangle GHI =6.5$
