FAQ

What is the difference between the perimeter and the area of a quilt?
The perimeter is the total length of the outer border around the quilt (measured in units like cm or m), whereas the area is the amount of surface enclosed inside the quilt (measured in square units).

If two rectangles have the same perimeter of 20 cm, do they have the same area?
Not necessarily: a 6 cm × 4 cm rectangle has perimeter 20 cm and area 24 sq cm, whereas an 8 cm × 2 cm rectangle also has perimeter 20 cm but area only 16 sq cm.
