![]() ![]() All of these are supported by this online area calculator. For right-angled triangles you can calculate the area by knowing the hypotenuse and the height towards it. There are multiple rules to calculate a triangle's area: SSS (side-side-side), SAS (two sides and the included angle), SSA (two sides and a non-included angle), ASA (two angles and the included side). ![]() Visual in the figure below:ĭespite the simplicity of the above equation, in specific situations you may not know these two exact measurements. The formula for the area of a triangle is height x π x (radius / 2) 2, where (radius / 2) is the radius of the base (d = 2 x r), so another way to write it is height x π x radius 2. Irregular shapes would often be broken down to a series of rectangles so that their area can be approximately calculated. It is one of the easiest figures to compute an area for. You need to take two measurements: the width and the height, and just multiply them together. The formula for the area of a rectangle is width x height, as seen in the figure below: ![]() However, since in most practical situations you need to measure both sides before you know it is a square, it might not be a huge difference, but at least it is easier to calculate. This is the simplest figure to calculate as all you need is a single measurement. The formula for the area of a square is side 2, as seen in the figure below: paint required), in land management, agriculture, biology, ecology, and many other disciplines. square centimeters, square kilometers, square inches, square feet, square miles.Īrea calculations have applications in construction and home decoration (e.g. The result is always a squared unit, e.g. How to calculate surface area of different 3D bodies. Surface body formulas and calculation examples. Radius of a circle having area equal to the sum of area of the circles having given radii. Find area of the larger circle when radius of the smaller circle and difference in the area is given. When taking measurements or reading plans, make sure all measurements are in the same units, or convert them to the same unit to get a valid result. Surface area calculator online - easyly calculate the surface area of a cube, rectangular prism, box, cylinder, sphere, cone, as well as triangular prism. Calculate Volume, Curved Surface Area and Total Surface Area Of Cylinder. See below for details on each individual one this area calculator supports, including the formula used. How to calculate the area of any shape?Įach geometrical figure has a different formula for calculating its area, and different required measurements that need to be known. ![]()
