This storyboard does not have a description.
Hey can you help me with my homework?
Sure what's it about?
Area of a rectangle
Oh that's easy, do you know the formula, A=bh and that area is the size of the surface of a shape?
No, but what do the letters mean?
Well, the A means area, the b means base, and the h means height.
Oh okay, so what do I do with them?
You multiply the the b and h.
How am I supposed to multiply letters?
You don't multiply the letters, you see the letters just represent the measurements of the sides of the rectangle.
That makes a lot more sense now.
Now since the base is 4 and the height is 10 that means the area of the rectangle is 40 cm2
