The length of the rectangle is 8 cm and the width is 2 dm. find its perimeter using the distribution

The length of the rectangle is 8 cm and the width is 2 dm. find its perimeter using the distribution property of multiplication.

For the convenience of the calculation, we will translate all the parameters of the rectangle into the same units of measurement – in centimeters. There are 10 centimeters in one decimeter, therefore, the value in decimeters must be multiplied by 10:

2 dm = 2 * 10 = 20 cm rectangle width

Now we find the perimeter by summing the length and width and multiplying by two:

2 * (20 + 8).

Using the distribution property of multiplication, open the parentheses and multiply the factor outside the parentheses by each term in parentheses:

40 + 16 = 56 cm perimeter of the rectangle.

Answer: the perimeter of the rectangle is 56 cm.
