Area = Side2 = 20*20 cm2 = 400 cm2
If the diameter of a circle 20 cm is tripled the area will increase from 314.2 cm2 to 2,827 cm2
20 cm x 20 cm = 400 cm2
500 cm2
I regret that I have no idea how a box can have a volume of 20 cm2 since that is not a unit which can be used to measure volume.
6*20*20 cm2 = 2400 cm2
Area = Side2 = 20*20 cm2 = 400 cm2
1 * 11 = 11 cm2 2 * 10 = 20 cm2 3 * 9 = 27 cm2 4 * 8 = 32 cm2 5 * 7 = 35 cm2 6 * 6 = 36 cm2 7 * 5 = 35 cm2 8 * 4 = 32 cm2 9 * 3 = 27 cm2 10 * 2 = 20 cm2 11 * 1 = 11 cm2

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 .
20 cm x 20cm = 400 cm2 . 400 cm2 x 6 = 2400 cm2.
20 cm x 20 cm = 400 cm2
500 cm2
Area to be covered = 500*400 cm2 = 200000 cm2 Area of tile = 30*20 cm2 = 600 cm2 So number of tile required = 200000/600 = 333.3.. that is, 334 tiles.
20 cm x 15 cm = 300 cm2
The area of a circle with a diameter of 20 cm is: 314.2 cm2
