There are different formulas for different figures.
Some of the most common are:
triangle = half base times height, or 1/2*b*h
square = length times width, or l*w
rectangle = length times width, or l*w
circle = pi times radius squared, or pi*r^2
trapezoid =half the height times the sum of the bases, or h/2 (b1 + b2)
ellipse = pi times the product of radius one and radius two, or pi*(r1*r2)
parallelogram = base times height, or b*h

What is the formula for finding the area of an irregular figure?
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.
How do you find the area of a scalene triangle?
Use Heron's Formula
What formula can you use to find the area of a trapezoid?
leanth times width
What is the formula to irregular figures?
If the figure is irregular, you can't calculate its area (for example) with some simple formula. You need to use integration - which basically means to divide the figure into many narrow strips, which you assume to be rectangles.
How do you figure area of a non geometric 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. Then add up all the areas to find the area of the original shape.

How do you find an area from perimeter?
Depends on what figure you are working on, each figure has its own formula for the area. So you need to do a sketch and label the relevant quantities which are needed to find the area. By using the perimeter value, find a formula for one quantity in terms of the other(s). Write the area as a function of just one variable. Find the domain of that variable. After that, use the derivative to find the desired global maximum or minimum (the highest or lowest points on the curve), which will give you the maximum or the minimum area of the figure you are interested in. If you have a specific problem, I can help more.
How can you use formulas to find the volume or surface area of a geometric figure?
The formulae will contain variables representing measure of the figure: the lengths of sides, vertical distance between sides or a point and a side, angles and so on. Find their values for the figure - by measurement, if necessary - and substitute ino the formula. Evaluate [work out the value of] the formula.
What is the formula to find the area of the base of a rectangular prism?
If the base is a rectangle, use the formula for the area of a rectangle.
How do you figure out the area of a triangle that is NOT a right triangle?
Use the formula 1/2 the base * the height
How can you calculate the surface area of a diameter?
You didn't specify what figure you are talking about. Assuming a circle: divide the diameter by 2 to get the radius. Then use the well-known formula area = pi x radius2.You didn't specify what figure you are talking about. Assuming a circle: divide the diameter by 2 to get the radius.

How do you figure out surface area for half sphere?
To do this question, we have to ask ourself, what formula do you use to find the surface area of a sphere. The answer should be known to you, but it is 4πr2. Since we know how to find the surface area for a full sphere, then finding the surface for a half sphere is just half the job. You use the formula for the full sphere 4πr2, and divide it by 2... so (4πr2) / 2 . Voila!
