If you mean that the square has side equal to 20 cm, then the area is 20 x 20 = 400 square cm
It means an area of 27 x 36 = 972 square cm
As we know, 1 ft = 30.48 cm 1 square ft=(30.48)2 square cm =30.48*30.48 square cm =929.0304 square cm
Assuming by "equal" you mean that each side is 5 cm, then the perimeter of a square is 5 cm * 4 (sides) = 5 cm + 5 cm + 5 cm + 5 cm = 20 cm The perimeter of any polygon is the sum of the sides Alternatively if by "equal" you mean the sides sum to 5 cm, then the perimeter is 5 cm. Although this is probably not what you meant =)
There is no such square with those dimensions but if you mean a rectangle then 12*6 = 72 square cm
If you mean that the square has side equal to 20 cm, then the area is 20 x 20 = 400 square cm
We have no idea what "a 144cm square" means. If you mean to say "a square with an area of 144 square cm", then its side length is 12 cm.
I assume you mean the SIDES are 7.6 cm. In that case, the area of the square is 57.76 cm2.
It means an area of 27 x 36 = 972 square cm
Do you mean 25 cm squared? If so then the answer is 5 cm
As we know, 1 ft = 30.48 cm 1 square ft=(30.48)2 square cm =30.48*30.48 square cm =929.0304 square cm
Do you mean 100 square centimeters? 1 inch = 2.54 cm, so 1 foot = 30.48 cm, so 1 square foot = 929.0 square cm. Thus 100 sq cm = 100/929 sq ft = 0.1076 sq foot
Assuming by "equal" you mean that each side is 5 cm, then the perimeter of a square is 5 cm * 4 (sides) = 5 cm + 5 cm + 5 cm + 5 cm = 20 cm The perimeter of any polygon is the sum of the sides Alternatively if by "equal" you mean the sides sum to 5 cm, then the perimeter is 5 cm. Although this is probably not what you meant =)
It is an area measurement. Think of taking 15 1x1 cm square tiles and putting them all in a row. The area of that row if 15 cm long and 1 cm wide so it is 15 cm squared.
There is no such square with those dimensions but if you mean a rectangle then 12*6 = 72 square cm
cm square x 0.0001 = meters square
That's virtually impossible to say until you explain what you mean by the 'radius' of a square.
