Question

find the area of triangle whose vertices are (-2,1),(0,2),(1,1)​

Answer 1

Answer:

Area of given triangle is 1/2 sq units

Step-by-step explanation:

area of triangle= 1/2 | x1(y2-y3)+x2(y3-y1)+ x3(y1-y2) |

(x1,y1)= (-2,1)

(x2,y2) = (0,2)

(x3,y3) = (1,1)

area of triangle= 1/2sq units
