How many square centimetres in a rectangle?
The length in centimetres multiplied by the width in centimetres will give you the area in square centimetres.
What is the side length of a square with an area of 25 square centimeters?
If the area is 25 centimetres, then the length of a single side will be sqrt(25) = 5 centimetres.
What happens to the area of a square when the measurement of its side is doubled?
If a square has a side length of 4 centimetres, then its area is equal to 4 x 4 = 16cm2 (16 square centimetres).If a square has a side length of 8 centimetres, then its area is equal to 8 x 8 = 64cm2 (64 square centimetres).Therefore, by doubling the side length of a square, the squares area quadruples.
What is the area of a square if it has a perimeter of 16 square centimeters?
A perimeter is a measure of length and so cannot be 16 square centimetres - which is a measure of area. As it happens, a square with a perimeter of 16 centimetres will have sides of 4 cm and so an area of 16 square centimetres.
What is the area of a square whose side is 4 centimeters?
A square with side length 4 centimetres has an area of 4 x 4 = 16 cm2 (16 square centimetres).
