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. Compute higher derivatives: second derivative of sin. Calculate the derivative of a function: derivative of x4 sin x. With the ability to answer questions from single and multivariable calculus. Answers for integrals, derivatives, limits, sequences. In addition to using integrals to calculate the value of the area, WolframAlpha also plots the curves with the area in question shaded. Calculus and analysis calculators and examples. The formula for the area of a rectangle is width x height, as seen in the figure below: WolframAlpha can calculate the areas of enclosed regions, bounded regions between intersecting points or regions between specified bounds. 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. It works as a definite integral calculator as well as an indefinite. Multiply these two values: A 5 cm × 6 cm 30 cm. Integral calculator is an online tool that calculates the antiderivative of a function. Decide on the rectangle's width for example, b 6 cm. The result is always a squared unit, e.g. Rectangle calc: find A (area) As we know the formula for the area of a rectangle A a × b, let's show with an example how you can calculate that property: Choose the length of the rectangle for example, a 5 cm. 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. See below for details on each individual one this area calculator supports, including the formula used.
