Answer 1

Answer:

It is 4 sq units

Step-by-step explanation:

Hi viewer,

we are given 3 points A(4,3),B(5,4) and C(11,2)

ar of triangle

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

=1/2 | 4(4-2)+5(2-3)+11(3-4)|

=1/2 | 4 (2) + 5(-1)+11(-1)|

=1/2 | 8-5-11|

=1/2 | -8 |

=1/2×8

=4 square units

Hence the area of triangle is 4 sq units

hope it helps!!
