What is the perimeter of a rectangle of 20cm2?

To determine the perimeter of a rectangle, we need both the length and width. The area of the rectangle is given as 20 cm², but without the specific dimensions, we cannot calculate the perimeter directly. For example, if the rectangle has a length of 5 cm and a width of 4 cm, the perimeter would be 2(5 + 4) = 18 cm. Thus, the perimeter varies depending on the rectangle's dimensions.

What is the perimeter of a 50cm2 rectangle?

To find the perimeter of a rectangle, you need both the length and the width.

For example, if the rectangle is 5 cm wide and 10 cm long, the perimeter would be 30 cm. If you provide either the length or width, I can help calculate the perimeter!
