Answer 2

Perimeter of a Quadrilateral

To find the perimeter of a quadrilateral with two sides measuring 30 millimeters each and two other sides measuring 20 centimeters each, we need to convert the measurements to the same unit before calculating the perimeter.

Let's convert the 20 centimeters to millimeters, so that we have all measurements in millimeters:

- 20 centimeters = 20 * 10 = 200 millimeters

Now we have two sides measuring 30 millimeters each and two sides measuring 200 millimeters each.

To find the perimeter, we add up all the side lengths:

Perimeter = 30 + 30 + 200 + 200

Simplifying the expression, we get:

Perimeter = 460 millimeters

Therefore, the perimeter of the quadrilateral is 460 millimeters.
