In a triangle, a = i ^ − j ^ + k ^ is a side and b = 2 i ^ + 4 j ^ + 3 k ^ is the median from the same vertex. The area of the triangle is

If the other side is c , then b = ( a + c ) /2 . Area = 2 1 ∣ a × c ∣ = ∣ a × b ∣ = 86 .

In a triangle, $a = \hat{i} - \hat{j} + \hat{k}$ is a side and $b = 2 \hat{i} + 4 \hat{j} + 3 \hat{k}$ is the median from the same vertex. The area of the triangle is

Options:

Answer:

Solution:

If the other side is $c$ , then $b = (a + c) /2$ . Area $= \frac{1}{2} ∣ a \times c ∣ = ∣ a \times b ∣ = 86$ .
