Use a ruler or tape measure to measure it.
The perimeter will be 12 cm
It is 12 cm because 102 mm = 10.2 cm
you must know the length of the rectangle as well in order to fill in the equation A=lengthxWidth
Nothing since there is no such thing as centimeteres. A cubic centimetre is the same as a millilitre.
If the length of a rectangle is 12 and the width of the rectangle is 16, by the Pythagorean theorem we know that one diagonal is 20 units long. You can draw two diagonals within a rectangle, so the length of both diagonals together is 20+20 = 40 units.

A rectangle has dimensions 7 ft x 12 ft. Which of the dimensions describe a rectangle that is similar to this rectangle?
If a rectangle is 40 inches. the rectangle is 12 inches long then: 2 * 12 + 2 * width = 40 2 * width = 40 - 2*12 = 40 - 24 = 16 width = 16 / 2 = 8 So the width of the rectangle is 8.
A 9 x 12 rectangle has a diagonal of 15.
there is no base for a rectangle. only triangles do. to know the sides of the rectangle you need to know the length and width of it
