How do you make a rectangle with the same perimeter but different area?
You just have to change the lengths of the sides. For example, if you wanted a perimeter of 20, your rectangle could be... 1x9 with area of 9 2x8 with area of 16 3x7 with area of 21 4x6 with area of 24 5x5 with area of 25 All of these have the same perimeter, but a different area, see?

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 rectangle whose perimiter is 42 cm?
The area can't exactly be determined here since we don't have enough information about the sides of the rectangles! We only know that the perimeter of the rectangle is 42 cm. Then: P = 2(l + w) where l is the length and w is the width. 42 = 2(l + w) 21 = l + w Solve for either w or l to get... w = 21 - l So by the area of the rectangle, we obtain: A = lw A = l(21 - l) = 21l - l² So we can't really determine the area of the rectangle. It's just the general form of the rectangle with the perimeter 42 cm.
