please heeeelp

To answer the problem above, kailangan natin ng drowing....hehehe

The figure that describes the problem looks like this:

To get the distance between points $A$ and $D$, we need to get the $s$ first. Using the Pythagorean theorem:

$$s^2 = (10 \space cm)^2 + (8 \space cm)^2$$ $$s = 12.8 \space cm$$

Now getting the distance between points $A$ and $D$ (denoted as $h$) using the Pythagorean theorem:

$$h^2 = (12.8 \space cm)^2 + (18 \space cm)^2$$ $$h = 22.1 \space cm$$

Therefore, the distance between the points $A$ and $D$ is $\color{green}{22.1 \space cm}$

Alternate solutions are encouraged....heheheh
