Question

The area of the triangle with vertices (3,0),(7,0) and (9,2) is?​

Answer 1

Answer:

area of triangle =8cm

Answer 2

Answer:

1/2|x1(y2-y3)+x2(y3-y1)+x3(y1-y2)| here mod is applied bcuz area is always positive

Step-by-step explanation:

here the formula is given above

x1=3,x2=7,x3=9

y1=0,y2=0,y3=2 from the vertices

therefore now put these values in formula

1/2|3(0-2)+7(2-0)+9(0-0)

1/2|-6+14+0|

1/2|8|

1/2×8 = 4

hope it helps
