Square metres, cubic metres
 
6 . Find the area of this rectangle.

We don't measure the area of a plane figure directly, but we do the necessary lineal measurements first and then we perform the suitable calculations depending on the figure.
To find the area of a rectangle, you only have to multiply the length by the width.
  Esta unidad interactiva requiere la máquina virtual de Java J2RE.

Find the area of this rectangle; do the necessary measurements with the ruler.
You can move the rulers from their ends, one after the other.
Do the calculations, type the number in the window, then hit Enter. Drag the correct unit to each yellow circle. You can express it in square centimetres and square millimetres.
When your answer is correct, the rectangle will appear divided in square centimetres or square millimetres, depending on the unit you have used.
