Answer 1

length.

Answer 2

(1) What measurement do you use to masure a perimeter? You measure the Circumference = 2 pi x r(adius). It's length is given in units of measurement that you are using. Common units of measurement are; in, ft, cm, m

(2) Which of the metric units is the shortest?
A metric unit is alway again divisble by 10, so there is no theoretical smallest measurement, when measuring wavelengths it is not uncommon to see nano-meters 10^-9 meters (.000000001 meters)

practical measurement on a ruler is mm (milli-meters) which 1/10 of a cm, or 1/100 of a meter

(3) What does a inch measures?

One inch is a predetermined amount of length in the British measurement system, which when compared to a cm = 2.54 cm. Normally broken into smaller increments of 1/2, 1/4, 1/8 and so on.

(4) How long is a tooth brush?

Depends on the toothbrush manufacturer and the age of the person it is intended for. My electric toothbrush is 8 7/8"

(5) What is the height of a classroom door?

Probably around 80" to 81" which is a normal door height. If this is a class assignment, you are going to have to measure your classroom door for a correct answer.

Answer 3

1. Perimeter is the distance around a figure say square, triangle, rectangle etc. To measure the perimeter, you just add the lengths of the sides.
The units of perimeter are mm, cm, m, km
2 and 3. An inch measured as 1/16".
4. Measure it with a tape with unit CM
5. Do the same as above and meaure it with CM or meter or ft

Answer 4

There are some really damn small metric units. Depends on what you mean.

1-Just use length... you can measure in meters, inches, or whatever you want.
2-A nanometer is 1^-9 meters. So that's pretty damn small.
3-An inch measures a lot of things.... length, mostly.

4, 5-DO IT YOURSELF. Toothbrushes are different sizes, so are doors. My guess is this is a class project, so you really just have to take a ruler out and measure it yourself. Also, roughly 39 inches = 1 meter.
