The length of the rectangle is 1 m 50 cm, and the width is 9 dm. The area of the rectangle is calculated.

We translate the length and width of this figure into the same size. Let’s translate all centimeters.

1 meter 50 cm = 1 * 100 cm + 50 cm = 150 cm – is the length of the rectangle.

9 dm = 9 * 10 cm = 90 cm – becomes the width of the figure.

Next, subtract area, remembering that area is the length of the rectangle multiplied by its width.

The area is designated by a capital S.

S = 150 cm * 90 cm = 13500 cm2.

We translate the area into dm2 – 13500/10 = 1350 dm2.

Now we represent the area in m2.

1350 dm2 / 10 = 135 m2.
