Yes, the ruler does need to be straight when finding or measuring the length of a country on a map. If the distance curved, you can use a string and the ruler to measure the length.
the measure of a straight-line distance between two points is called length.
You don't. Diameter is a measure of length, not area.
False
To accurately measure the length of an arrow, use a ruler or measuring tape to measure from the tip of the arrowhead to the end of the shaft. Make sure to measure in a straight line for the most precise measurement.
To accurately measure the length of a stem, use a ruler or measuring tape to measure from the base of the stem to the tip. Make sure to measure in a straight line for the most precise measurement.
To measure a men's coat length, lay it flat and measure from the base of the collar down to the hem. This will give you an accurate measurement of the coat length. Be sure to measure straight down the back of the coat for an accurate measurement.
Length is a physical quantity that measures the extent of something along a straight line. Common units used to measure length include meters, centimeters, inches, and feet. Length is commonly used to describe the size and distance of objects.
Length is usually a measure of distance in a straight line. Girth is the distance around a [solid] object.
Multiply the Length by the Width by the Height. Measure one edge. Cube the number.
P = 2L + 2W P = 2(L + W) P/2 = L + W If the perimeter is given and you know one of the side measure length (i.e mL), then you can find the measure length of the other sides. If you know the measure length of L, then the measure length of W is P/2 - L = W,and vice versa.
Ah, measuring a straight line is quite simple, my friend. You see, the measure of a straight line is its length from one end to the other. Just take a ruler or a measuring tape, place it at one end of the line, and extend it all the way to the other end. That's the measure of your straight line, and it's as beautiful as a happy little tree.
use a ruler!!!!how do you use a ruler with a semicircle EDIT: Assuming you can measure the length of the straight side.. to find the perimeter - treat it as a whole circle, and find the circumference through multiplying the diameter (straight edge) by Pi. Then - divide that figure by 2, and add on the length of the straight side ! Snakester1962 (Supervisor)
