A basic geometry skill such as finding the area gives you detailed measurements of large, life scale surfaces in a fraction of the time it may take you to measure the whole thing by hand, yourself. Examples would be, the height of a flag pole, or the size of a room that needs to painted. Also, a theater may need to know the area of its room to work on the sound system and make it acoustically sound.

How do you find out the height from the area?
You must know what type of geometric shape it is. However, if it is a rectangle (and you know the width), then then the formula is Area/Width=height. Edit your question if it is a different shape.
How do you find the perimeter if you know the area and length?
You have to add up all the sides of the shape.
Why would you need to find area?
If you need to find how big something 2-D is you need to know how to find the area of various shapes. If carpeting you need area. You don't think about it but area is very important. Math isn't useless and is very important int he real world.
Why is it important to know how to find area and perimeter?
Look how many questions there are on this site from people who can't.
How do you find the area and perimeter if the figure does not have equal sides?
For the perimeter, you just go round the shape, adding the lengths of each side as you go along. There may or may not be simple formulae of the area for a shape with unequal sides. If all you know is the [different] side lengths then only a triangle has a relatively simple formula for its area. If you also know that some of the sides are parallel, then you can find the area of a rectangle. Then, if you also know the perpendicular distance between the parallel sides, you can do a parallelogram. If, in addition you know which sides are parallel, a trapezium. And so on.
Beneficial to know the area of a shape?
well it is benificial to know the area of a shape because to find the circumference, radius, and diameter u must know the area of the shape well it is benificial to know the area of a shape because to find the circumference, radius, and diameter u must know the area of the shape
How do you find the dimensions of a shape if all you know is the area?
You cannot.
Why would it be beneficail to know the area of a shape?
It would be benifical to know the area of a shape because without it you cant find the diameter radius or circumference
How do you find out the height from the area?
You must know what type of geometric shape it is. However, if it is a rectangle (and you know the width), then then the formula is Area/Width=height. Edit your question if it is a different shape.
How can you find the area if you know the perimeter?
Only if you also know the shape and proportions. An equilateral triangle, for example.
How do you find the perimeter if you know the area and length?
You have to add up all the sides of the shape.
When you find the area of a shape do you times the width by the length then divide it by 2?
I cannot answer this question because I don't know what the shape in question is.
What is the easiest way to find surface area?
For a regular shape there are certain formulae for calculating area. You will need to learn, or know where to find these. With irregular shapes it becomes more difficult.
How do you find the total area if you only know the height and radius?
It depends on the shape for which you want the area. The area of both cones and cylinders are completely defined by height and radius.
How do you find the area of a number?
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.

What do I know about area?
area is the outside of a polygon or some kind of shape.
