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.

What are all the odd square numbers?
There are infinitely many of them. The square of every odd number will be an odd square number.
What is a odd square number?
The square of any odd number will be an odd square number. eg 12 = 1 32 = 9 52 = 25 etc
How will you know that the root of a given number is even or odd?
Assuming you know that your number is a perfect square, the square root of an even number is even, and the square root of an odd number is odd.
How do you find the dimensions of a rectangle that has an area of 120 square inches if the length is one inch smaller than twice the width?
you can't, unless the area was an odd number you can't, unless the area was an odd number
What is the square footage of a room 20x17x8?
To figure out the square footage of this odd sized room, you simply need to multiply the numbers. The answer is 2720 square feet.
What the Square meter of an odd shape?
Break up the odd shape into even shapes and add the areas.
How do you know if you have 2 acre of land?
Measure two adjacent sides of your piece of land if it's square, rectangular, or a parallelogram in shape. Multiply those two numbers (in feet). If the number you get is less than 87,120, then you don't have two acres. If you have an odd-shaped piece of land, you will need to find a way to find out the square footage.
How do you find the sq ft of a floor?
Measure the length of the room in feet (12 inch increments) and then the width of the room in feet (12 inch increments). Next multiply the length by the width and you will have the square footage. If your room is an odd shape then break it down into quadrilateral shapes (squares and rectangles) measure length and width of each, multiply, and add the totals together for total square footage of a room.
How do you find the perimeter of an odd shape?
All you do is add up all the sides to find the perimeter even though it is a odd shape
How do you get the square footage of a odd shaped room?
You divide it up into regular shapes: rectangles, triangles, semicircles. Then use the formulae for these shapes and add the results together. If you cannot do that - because the shape is just too irregular, draw a scaled version of the shape on a board of uniform thickness. Cut the shape out and find its mass (or weight). Also, draw a square foot on the board to the same scale and get its mass. The square footage of the room is the ratio of the masses (or weights). You could also draw a scaled version of the room on a grid representing a unit area. Count the number of squares that are at least half inside the sketched room. Ignore all squares that are less than half inside. The number of squares inside multiplied by the square footage of each square will give the approximate area of the room. The finer the grid, the more accurate the result (but it will also be harder work).
