Answer:
15
Step-by-step explanation:
Area of triangle by coordinate (x,y) of 3 vertex
Area = abs(x₁ (y₂-y₃) + x₂ (y₃-y₁) + x₃ (y₁-y₂)) / 2
A (-2,3) B (4 , 3) C (-1 , -2)
Area = abs(-2 (3 - -2)) + (4 - (-2 - 3)) + -1 (3 - 3)) / 2
= abs (-10 - 20 + 0) / 2
= abs (-30) / 2
= 30/2
= 15
wish this help, if you are happy.. give me a happy face on "comment". No star or brainliest please.
*Easy approach: AB parallel to X axis
base AB = (4- -2) = 6
height C to AB: 3 - (-2) = 5
area = 6 x 5 / 2 = 15
