Question

P(5,6), Q(-2,-7) and R(0,8) are three vertices of a triangle. What is the area of the triangle PQR (sq. unit)?​

Answer 1

Answer:

area of triangle

Step-by-step explanation:

area of triangle=✓x1(y2_y3)+X2(y3_y1)+X3(y1_y2)

=√5(-7-8)-2(8-6)+0(6+7)

=√5(-15)-2×2

=√-75-4

=√-79

which is not possible because area of triangle be never negative.
