Question

The area of triangle ABC is?

Answer 1

`A(\triangle ABC) =17.5 \: {units}^(2)`

Explanation:

AB = 4 - (-3) = 4 + 3 = 7 units

BC = 3 - (-2) = 3 + 2 = 5 units

`A(\triangle ABC) = (1)/(2) * AB* BC \\ \\ A(\triangle ABC) = (1)/(2) * 7* 5 \\ \\ A(\triangle ABC) = (1)/(2) * 35 \\ \\ A(\triangle ABC) =17.5 \: {units}^(2)`
