Question

find the area of the triangle whose verticals are (2,3) (-1,0) (2,-4).plzz answer me fast?​

Answer 1

Answer: PLEASE BRAINLIEST MY ANSWER

∵ The area of a triangle is 21/2sq.unit

Step-by-step explanation:

(i) Let A(2,3), B(−1,0) and C(2,−4) are the vertices of △ABC

Area of triangle=  1/2 [x1 (y2 −y3) + x2 (y3 −y1 ) + x3 (y1 −y2)]

Here (x1 ,y1)=(2,3)

(x2 ,y2)=(−1,0)

(x3,y3 )=(2,−4)

∴ area(triangle) =   1/2  [2(0+4) − 1(−4−3) + 2(3−0)]

=  1/2  [8+7+6]

=   21/2sq.unit

∵ The area of a triangle is 21/2sq.unit
