You get the area by using formulas. There is usually a specific formula to find the area of each shape. Some irregular shaps may not have a formula.
The formula will depend on what it is that you are trying to find: the volume or the surface area.
The formula to find the area of an octagonal pyramid is area of base plus area of sides.
The formula for the area of a parallelogram: Base times Height (BH)
find the area of all the faces then add them all up. this is how you get surface area and there isn't any formula for it
i dont no if you can find the perimeter of a triagle by using subtration the formula is adding all the up together.
The area doubles.
distance of all sides added togather
The formula to find area is you do the radius squared times pi or 3.14
The area formula for the parallelogram is related to the area formula for a rectangle because you can make the parallelogram into a rectangle to find the area.
A formula is needed to find the area of a parallelogram. It is a very simple formula which notates Area = base x height.
The formula for the area of a quadrilateral is... BASE*HEIGHT/3
The formula to find the area of a circle is: A = pi * r2
In order to find the area of parallelogram is found by knowing the area formula. The formula is A=b(base) multiplied by H(height).
Area of a triangle = (base x height)/2 If the pyramid is made up of four identical triangles then it's surface area will be 2 x base x height. Remeber the height is the distance from the base of a triagle to the oposite point.
Area of what? Every geometrical shape has a different formula to find its area. The simplest one: to find the area of a rectangle whose edge lengths are h and w, area = h*w.
The area of a circle can be found with the formula (pi)r^2
