It is a term that is not properly defined. It could, most likely, refer to a line that is 1 unit long, or a square that is 1 unit*1 unit, or a cube of sides 1 unit, or indeed a hypercube in higher dimensions
The unit in question would normally be a standard measure of length such as a centimetre, metre, kilometre, inch, foot, mile, light year, parsec. But, equally, it could be the length of the little finger on your right hand!
it depends on the shape. the unit should be given
There are different formulae for different shapes. Try to break down the composite firgure into components that you can add together (or subtract one from the other). An annulus, for example, is a big circle minus a smaller circle. Areas of squares, triangles, trapeziums, circles, semicircles and the process described anove will answer most high school questions. For more complex figures you may need to look elsewhere. Copy the shape onto a lamina of uniform density. Cut out the shape and find its mass. Also find the mass of a unit square of the lamina. Then area of composite shape = size of unit shape*mass of composite shaped lamina/mass of unit shape.
To find the area, first divide the shape into regular, simple shapes. Then use formulas to find the area of the smaller, regular shapes. Lastly, add up all the smaller areas to find the area of the original shape.
Pick a unit. Draw a square that has two of those units on each side.
regular shape is a shape that has same sides irregular shape is a shape that has diffrent sides
Yes a unit for measure can be used as a tessellating shape:)
it depends on the shape. the unit should be given
An arb. unit is an arbitrary unit. You see these in plots where the specific values are not of important, but the shape of the curve is.
Yes.
polygon a shape
you do not, one is a unit of measure, the other is a shape.
A decimetre is not a shape but a unit for measuring length. A centimetre and millimetre are smaller as are micrometres, nanometres and others.
1) because the unit has a bulbous shape (the outer glass bit) 2) because the unit produces/emits light. The name is an exact description of that it does and its shape.
Cubic centimeter.
density
Nothing. Since density is defined as the mass per unit volume. Shape is different from size. Size, of course, is related to the volume. Hence Shape is irrelevent.
The area of any shape should be in SQUARE unit, and not only unit. So the question is wrong!
