To find the area of a rectangle, you multiply its length by its width. Given the area of 20 cm², we need to find two numbers that multiply to 20. The possible dimensions are 4 cm by 5 cm or 2 cm by 10 cm. To find the perimeter of a rectangle, you add up all its sides. With a perimeter of 18 cm, the possible dimensions are 4 cm by 5 cm, as 4 + 5 + 4 + 5 = 18 cm.

BlakeOh, isn't that just a happy little question? To find the area of a shape, we look at how much space it covers. And to find the perimeter, we add up all the sides. So, for a shape with an area of 20 cm² and a perimeter of 18 cm, we would need more information about the shape to calculate those values. But don't worry, we can paint a beautiful picture with math once we have all the details!

What is the area of a perimeter of 20 centimeters?
The perimeter and area don't depend on each other. Knowing one doesn't tell you the other. -- A circle with perimeter (circumference) of 20 cm has area of 31.83 cm2. -- A square with perimeter of 20 cm has area of 25 cm2 . -- A (9 x 1) rectangle has perimeter of 20 cm and area of 9 cm2 . -- A (8 x 2) rectangle has perimeter of 20 cm and area of 16 cm2 . -- A (7 x 3) rectangle has perimeter of 20 cm and area of 21 cm2 . -- A (6 x 4) rectangle has perimeter of 20 cm and area of 24 cm2 .

What is the area of a square that has a perimeter of 80 m?
If a square has a perimeter of 80 meters, then each side is 20 meters in length. (80/4 sides of a square=20) The area of a square is side2, so 20*20 equals 400. The area of a square that has a perimeter of 80 meters is 400 meters2.
