Rectangles with a perimeter of 20 units can have various dimensions, as long as the sum of the lengths of all four sides equals 20 units. One example could be a rectangle with sides measuring 4 units by 6 units, as 4 + 4 + 6 + 6 = 20. Another example could be a square with sides measuring 5 units each, as 5 + 5 + 5 + 5 = 20. In general, rectangles with sides of any length that add up to 20 units can have a perimeter of 20 units.

How many rectangles can you find with a perimeter of 20 cm?
perimeter = 2 (b+h) = 20 there are an infinite number of rectangles that meet the requirement
What is the length of each side on a square with a perimeter of 80 units?
20 units.
Can you name the lengths of sides of three rectangles with the perimeter of 12 units using whole numbers?
1 unit x 5 units2 units x 4 units3 units x 3 units
Can rectangles with the same perimeter have different areas?
Yes. Say there are two rectangles, both with perimeter of 20. One of the rectangles is a 2 by 8 rectangle. The area of this rectangle is 2 x 8 which is 16. The other rectangle is a 4 by 6 rectangle. It has an area of 4 x 6 which is 24.
If the perimeter of a square is 24 square units what is the area?
36 square units. You can't express a perimeter in square units; a perimeter is a length expressed in ordinary units. If the perimeter of this square is 24 units then the answer above is correct.
