![]() Step 1: Find a smaller rectangle with unit fraction side lengths using the denominators of the side lengths. All of these are supported by this online area calculator.Find the area of a rectangle with the given dimensions. ![]() For right-angled triangles you can calculate the area by knowing the hypotenuse and the height towards it. The two most recently changed values are used, the other three are calculated live. 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). Rectangle Calculator (Area, Perimeter, Diagonal) Rectangle Calculator Enter any 2 of width, height, area, diagonal or perimeter. 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. Width Given Area Width Given Perimeter Length Given Area Length Given Perimeter. You need to take two measurements: the width and the height, and just multiply them together. Calculate width & length of a rectangle step by step. 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. meter), the area has this unit squared (e.g. The formula for the area of a square is side 2, as seen in the figure below: Calculations of geometric shapes and solids: the Curved Rectangle. Free fully automatically graded Python assignment on Rectangle Area Calculator as part of CodeGrades Introduction to Python curriculum with 40+ Python. paint required), in land management, agriculture, biology, ecology, and many other disciplines. To calculate the length and width of a rectangle first, calculate the value of width w by using the area of rectangle formula that is, w A/l. Solving math equations can be challenging, but its also a great way to improve your problem-solving skills. square centimeters, square kilometers, square inches, square feet, square miles.Īrea calculations have applications in construction and home decoration (e.g. Length and Width of Rectangle Given Area Calculator. The result is always a squared unit, e.g. 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. The area of a rectangle is the amount of two-dimensional space inside the boundary on rectangle. ![]() Use our length converter to convert your units to inches. All four interior angles of a rectangle are 90.(right angles). If your measurement is in another unit of measure, such as centimeters, then you’ll need to convert to inches first. See below for details on each individual one this area calculator supports, including the formula used. The first step to calculate the area of a rectangle in square inches is to measure the length and width of the area in inches using a ruler or tape measure. Area of rectangle length breadth Entering the values written above for the determination of area. ![]() 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.
