…and also whether we can just calculate area with some complex inputs.
So we should know that the formula for area of a triangle is base times height divided by 2, right?
If we don’t, we may want to take extreme measures to commit it to memory …
So draw the triangle and we have negative 3 positive 2, 11, 2 and 4, 7… there we go...
Here we can see that the base is given by this area – and we can count that it’s
14 units… and the height is 1 2 3 4 5.
So we just plug in the numbers to the formula and we get 14 times 5 over 2 or.. 35.
As in, “Cubism.”
