Answer 3

Do you know the pythagorus theorem?

Answer 4

Yeah, I'm a little rusty though. Could you refresh me on it?

Answer 5

Pythagorus' theorem, states that the in a right angled triangle,\[hypotenuse ^2 = base ^2 + perpendicular ^2\]

Answer 6

How does that translate to the perimeter of that figure?

Answer 7

It doesn't.

Look at the figure and each of its sides.

Carefully observe how each side actually looks like a hypotenuse and the grid lines the base and the perpendicular.



Getting this? :)
