Find the area of a rectangle if its length is 4 dm and its width is 2 dm 6 cm less than its length.

To solve the problem, you first need to determine the width of the rectangle.

To do this, subtract the difference from its length, which is 4 dm, which is 2 dm 6 cm.

For the convenience of calculations, we translate the value of the sides of the rectangle from decimeters to centimeters.

Since 1 dm – 10 cm, we get:

4 * 10 – (2 * 10 + 6) = 14 cm or 1 dm 4 cm. (Rectangle width).

Find the area of the rectangle.

To do this, we multiply its sides among ourselves.

In this case, we get:

40 * 14 = 560 cm ^ 2 or 5.6 dm ^ 2.
