Question

The area of the triangle whose vertices are A(1, 2), B(-2, 3) and C(-3, -4) is
(a) 11
(b) 22
(c) 33
(d) 21


Answer it with explanation​

Answer 1

Answer:

$\huge\pink{AnSwer}$

==> a) 11

Explanation :-

Reason: required Area =

$\frac{1}{2} [1(3 + 4) - 2( - 4 - 2) -3(2 – 3)]$

$= \frac{1}{2} [7 + 12 + 3]$

$= \frac{1}{2} \times 22 = 11$

Answer 2

Answer:

$\huge\mathcal\pink{AnSwer}$

==> a) 11

Explanation :-

Reason: required Area =

$\frac{1}{2} [1(3 + 4) - 2( - 4 - 2) -3(2 – 3)$

= $\frac{1}{2} [7 + 12 + 3]$

= $\frac{1}{2} \times 22 = 11$
