4 cm * 9 cm = 36 square cm.
You can't "change" centimeters to meters. But you can describe a length or a distance in terms of either unit. -- If you know the length in centimeters, divide that number by 100 to find the number of meters in the same distance. -- If you know the length in meters, multiply that number by 100 to find the number of centimeters in the same distance.
You divide centimetres by 10 So 5cm = 0.5dm
Divide the length you have measured in cm by 2.54 to get inches Multiply the length you have measured in inches by 2.54 to get cm
Either one is fine. But depending on what you're measuring, one of them will give you a convenient number, and the other one will give you an awkward number. Examples: The length of a small paperclip: 30 millimeters, 0.000003 kilometer The length of a major city block: 1,609,344 millimeters, 1.61 kilometers
Exactly the same as any other object. -- Describe its length in centimeters or millimeters. -- Describe its mass in grams. -- Describe its weight in newtons. -- Describe the amount of space it fills in milliliters or cubic centimeters. -- Describe its temperature in degrees Celsius. -- Describe the pitch of its teeth in reciprocal centimeters. -- Describe the total number of its teeth with a dimensionless number.
To have consistent units, just convert the centimeters to millimeters (multiply the number of centimeters by 10), and then multiply length x width.
It is 5!!!! It can be any number
You can't.There is a cheap way to do it, though. Say that two sides are 5 meters and that the other two sides are 250 centimeters. (2.5 meters is 250 centimeters)

What is this number and in which length unit?
It makes sense right up to the last sentence. This question is impossible to answer, since it is unclear in what it asks.
the answer to number 20 is B...12
To find the length of a diagonal in a rectangle, use the Pythagorean method. Diagonal length = square root(length squared + height squared).
It seems to me that you would not need to dream up any new-fangled sentence. All you need to do is focus your attention and take a good long look at the sentence that asks: "How many centimeters are there in 2 centimeters ?"
12 centimeters =
If the length and width of a rectangle are multiplied by the same number, then . . . -- the perimeter is multiplied by the same number -- the area is multiplied by the square of the numbner
4 times the number of tiles in the length of the rectangle.
