We're going to examine the formulas you will need to figure out the surface area and volume of three-dimensional shapes as well as the area and perimeter of two-dimensional shapes. You can study this lesson to learn each formula, then keep it around for a quick reference next time you n...
To find out the area of a composite or a compound shape, you must divide that shape into regular shapes and find the area of all the shapes and the total amount. The technique is similar to what you do for an irregular shape. Practice Problems: Area of composite shape = Area of rectan...

Formulas for Calculating Area We are surrounded by so many 2-D shapes: circle, triangle, square, rectangle, parallelogram, and trapezium. You can draw all of these shapes on your paper. Every shape is different and unique, so its area is also calculated differently. To find the area, first...
The lateral surface is the area of all the sides of the object, excluding the area of its base and top. This division is used for shapes which have an obvious distinction between base and the other part – e.g., for a cylinder, cone, a pyramid or a triangular prism. It’s rarely ...

area = 1 / 2bh Equilateral Triangle Area An equilateral triangle is one where all three sides are equal in length, and all three angles are 60°. Given an equilateral triangle, you can find the area using the length of one of the sides. The formula to find the area for an equilate...
The formulas for geometry are used to calculate the circumference, area, surface area and volume for closed two-dimensional and three-dimensional shapes and objects. What are the basic rules of geometry? Geometry studies shapes that are all closed by arcs or line segments. Two-dimensional figures...
The area of an object is entirely dependent on its shape and size. We can compute the area of many common shapes by using certain accepted formulas. Area Formulas Let’s have a look at the most common formulas for finding the area. To find the area of a rectangle shape, we use the ...
