How is the precision used in measuring the length and width of a rectangle related the precision of the resulting area measurement?
Roughly speaking, the percentage error when you multiply two numbers (measurements) will be similar to the percentage error of each of the individual numbers. Actually, the MAXIMUM percentage error can be approximately as much as the sum of the individual percentage errors, but the EXPECTED percentage error will be less than that.

What is the square unit of a 4 by 6 rectangle?
The square unit of a 4 by 6 rectangle is 24 square units. This is calculated by multiplying the length (4 units) by the width (6 units) of the rectangle. The resulting product represents the total area of the rectangle in square units.
If two rows of a determinant are interchanged what is true of the resulting determinant?
The resulting determinate is the negative, or opposite, of the original determinant.
If two rows of a matrix are interchanged what is true of the resulting determinant?
The determinant will change sign.

It is unknown for right now.
What determines the precision of a measurement?
The precision of a measurement is determined by the smallest increment that can be reliably measured by the instrument used. It is influenced by factors like the resolution of the measuring device and the skill of the person taking the measurement. A higher precision means the measurement has smaller increments or divisions, resulting in more accurate and detailed results.
What is 1.68metre squared?
1.68 meters squared is a unit of measurement for area. It represents the area of a square or rectangle with sides measuring 1.68 meters each. To calculate the area of a square or rectangle, you multiply the length by the width, so in this case, the area would be 1.68 meters multiplied by 1.68 meters, resulting in 2.8224 square meters.
Is it true that Precision is a measure of how close a resulting or measurement is to the accepted value of the quantity being measured?
Precision is a measure of how close repeated measurements are to each other. It does not take into account how close the average of those measurements is to the true or accepted value. Accuracy, on the other hand, is a measure of how close a measurement is to the true or accepted value.
When measuring resistance should there be a voltage applied to the resistor?
No, the meter used to make the measurement will be applying whatever voltage to the resistor it needs to make the measurement. Any additional voltage will disturb this, resulting in at least an incorrect reading and at worst damaging or destroying the meter.
A rectangle has a perimeter of 44 the dimensions of the rectangle are scaled by a factor of 1.5 so what will be the perimeter of the resulting figure?
44 x 1.5 = 66.
When calculating Newton's Second Law of Motion what is the resulting unit of measurement called?
The resulting unit of measurement when calculating Newton's Second Law of Motion is called a Newton (N).
Why is levelling important in surveying?
Leveling in surveying is important to get an accurate measurement. The rise and fall of the grade will cause the measurements to be off, resulting in an inaccurate measurement of plots of land.
What is the meaning of area in measurement?
Measuring "area" refers to determining size in two dimensions (e.g., length and width). The resulting measure is typically reported in terms of units of measurement "squared." For example, if a surface is one foot long and one foot wide, the area of the surface is called "one square foot" or "one foot squared."
What factors influence the precision of measuring tools?
Factors that influence the precision of measuring tools include the quality of manufacture, level of calibration, environmental conditions (e.g. temperature, humidity), and the skill of the operator using the tool correctly. Additionally, the resolution and design of the measuring tool can also impact its precision.
Why is it necessary to take both the vernier readings of theodolite?
Taking both the upper and lower vernier readings of the theodolite helps to eliminate any errors caused by misalignment or wear in the instrument, resulting in a more accurate measurement. Comparing the two readings can also help detect any potential issues with the theodolite's precision.
How does a gamma density meter work?
A gamma density meter works by measuring the level of gamma radiation that passes through a material. This measurement is then used to determine the density of the material being scanned. The higher the density of the material, the more gamma radiation is absorbed, resulting in a lower reading on the meter.
How do you calcuate the diagonal of a rectangle?
Since a diagonal divides a rectangle into two triangles, this is actually a problem in trigonometery. Since a rectangle has right angles, the resulting triangles also have right angles, therefore you can apply the Pythagorean Theorem. Or, just take your ruler and measure the diagonal. That's the direct approach.
