The area of the rectangle is 30 dm2; its width is 50 cm. Find the perimeter of this rectangle.

To calculate, the perimeter of this rectangle.

We first need to translate its area into square meters.

We know that 1 dm2 is equal to 100 cm2.

So we need:

30 * 100 = 3000.

Now let’s count the second side of the rectangle.

To do this, you need to divide the area into sides.

3000: 50 = 60.

Now let’s calculate the perimeter, add the two sides, and then multiply by 2.

50 + 60 = 110;

110 * 2 = 220.

Answer: The perimeter of the rectangle is 220 cm.
