In 620 square meters, there are no meters, as square meters are a unit of area, not length. Square meters measure the two-dimensional space within a shape, while meters measure length or distance. The square meter is the SI derived unit of area, with the symbol m², and it is defined as the area of a square with sides of one meter.
The answer depends on the nature of the complex shape. Some complex shapes can be decomposed into smaller shapes whose areas can be determined using standard formulae. It is then simply a question of adding the parts together. For more complicated shapes, there are essentially two options: you can either use uniform laminae and mass or estimate the area using grids.Uniform Lamina: Copy the shape onto a sheet (lamina) of material with uniform density. Cut the shape out carefully and measure its mass (or weight). Do the same for a unit square of the lamina. Then, because the lamina is of uniform density, the ratio of the two areas is the same as the ratio of the two masses. That is: Area of Shape/Area of Unit Square = Mass of Shape/Mass of Unit Square. Rearranging, and noting that the area of the Unit Square is, by definition, = 1 sq unit Area of Shape = Mass of Shape/Mass of Unit Square.Grid Method: Copy the shape onto a grid, where each grid square has an area of G square units. Count the number of squares that are fully or mostly inside the shape. Call this number W (for whole). Count the number of squares that are approximately half inside the shape and call this number H (for half). Ignore any square that are less than half in the shape. Then a reasonable estimate of the area of the shape is G*[W + H/2] square units. There is some arbitrariness about "mostly inside"Â and "approximately half"Â but there is no way around that. You will get more accurate results with finer grids, but they will also require much more effort in terms of counting the grid squares.

The area of any shape should be in SQUARE unit, and not only unit. So the question is wrong!
A unit square.
Area is the measure of the two-dimensional space enclosed by a shape or object. It is usually expressed in square units, such as square meters (m²) or square feet (ft²). Area is calculated by multiplying the length of a shape by its width.
Area units measure the amount of space that a two-dimensional shape covers. It is typically expressed in square units, such as square meters, square feet, or square centimeters. The larger the value of the area unit, the greater the space occupied by the shape.
There is no SI "base unit" for area. Originally there was a unit called an are which was equivalent to 100 square meters, but this has fallen out of favor. The hectare (100 are, or 10,000 square meters, or the area of a square 100 meters on a side) is also sometimes used, but it's not a base unit.Area is a derived quantity (from the unit for length), so the most appropriate SI unit for area is the square meter.
Square footage is a measure of area. There are formulae for some simple shapes but for more complicated shapes there are essentially two options: you can either use uniform laminae and mass or estimate the area using grids. Uniform Lamina: Copy the shape onto a sheet (lamina) of material with uniform density. Cut the shape out carefully and measure its mass (or weight). Do the same for a unit square of the lamina. Then, because the lamina is of uniform density, the ratio of the two areas is the same as the ratio of the two masses. That is: Area of Shape/Area of Unit Square = Mass of Shape/Mass of Unit Square. Rearranging, and noting that the area of the Unit Square is, by definition, = 1 sq unit Area of Shape = Mass of Shape/Mass of Unit Square. Grid Method: Copy the shape onto a grid, where each grid square has an area of G square units. Count the number of squares that are fully or mostly inside the shape. Call this number W (for whole). Count the number of squares that are approximately half inside the shape and call this number H (for half). Ignore any square that are less than half in the shape. Then a reasonable estimate of the area of the shape is G*[W + H/2] square units. There is some arbitrariness about “mostly inside†and “approximately half†but there is no way around that. You will get more accurate results with finer grids, but they will also require much more effort in terms of counting the grid squares.
It depends first of all on whether or not the decagon is regular. If it is not regular, there are two main options: one is to divide it into sections for which there are simple formulae, and sum the results. The alternative is to copy the shape onto a lamina of uniform mass, measure the mass (or weight) of the shape and of a square of unit size and use the ratio of the masses to estimate the area of the shape. Area of shape = (Mass of copied shape/Mass of unit square)*Area of unit square The last term has value 1, but is included so that the equation is balanced in its dimensions. If the shape is regular, then it depends on what information is given.
Square feet are a measurement unit for area. It is not clear what shape the three numbers in the question refer to.
I do not believe that it can be done. You can get an estimate using either of the following methods:Uniform Lamina: Copy the shape onto a sheet (lamina) of material with uniform density. Cut the shape out carefully and measure its mass (or weight). Do the same for a unit square of the lamina. Then, because the lamina is of uniform density, the ratio of the two areas is the same as the ratio of the two masses. That is: Area of Shape/Area of Unit Square = Mass of Shape/Mass of Unit Square. Rearranging, and noting that the area of the Unit Square is, by definition, = 1 sq unit Area of Shape = Mass of Shape/Mass of Unit Square. Grid Method: Copy the shape onto a grid, where each grid square has an area of G square units. Count the number of squares that are fully or mostly inside the shape. Call this number W (for whole). Count the number of squares that are approximately half inside the shape and call this number H (for half). Ignore any square that are less than half in the shape. Then a reasonable estimate of the area of the shape is G*[W + H/2] square units. There is some arbitrariness about “mostly inside†and “approximately half†but there is no way around that. You will get more accurate results with finer grids, but they will also require much more effort in terms of counting the grid squares.
Any [unit of length]2 is a unit of area. Some popular ones are -- square inch -- square foot -- square yard -- square centimeter -- square meter -- hectare -- acre -- section. The shape of the area doesn't matter. It doesn't even have to be flat.
A metric square measure is called a square meter (m²). It is the standard unit of area measurement in the metric system.
Square feet is a measure of area, not distance, so it cannot be directly converted to miles. It would depend on the shape and dimensions of the area being measured to determine how many miles it would cover.
