An 8x5 rectangle. If the bottom left corner is considered (0, 0), then two lines are drawn within the rectangle, from (0, 4) to (8, 1) and from (1, 5) to (7, 0). The smaller two regions of the four these lines cut the rectangle into are shaded. What is their combined area?

    It’s 6.5

    | 0  5  1 |   | 0   4   1 |
| 0  4  1 | + | 4  2.5  1 | = 6.5
| 1  5  1 |   | 1   5   1 |

    Determinants go brrr
