Answer 1

Answer:

Area of the triangle formed by the points (0,0),(x,0),(0,y)=

2

1

∣xy∣sq.units

Area of the triangle formed by the points (0,0),(4,0),(0,3)=

1

(12)

=6 sq.units

Answer 2

Answer:

x1,y1=0,0

x2y2=4,0

x3,y3=0,4

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

=1/2*(0(0-4)4(4-0)0(0-0)

=1/2*0(-4)4(4)0(0)

1/2*16

=8

ans is 8
