…and also whether we can just calculate area with some complex inputs.

00:34

So we should know that the formula for area of a triangle is base times height divided by 2, right?

00:40

If we don’t, we may want to take extreme measures to commit it to memory …

00:48

So draw the triangle and we have negative 3 positive 2, 11, 2 and 4, 7… there we go...

00:55

Here we can see that the base is given by this area – and we can count that it’s

00:59

14 units… and the height is 1 2 3 4 5.

01:03

So we just plug in the numbers to the formula and we get 14 times 5 over 2 or.. 35.
