![]() The formula states that \(A=l\times w\), so the area of the yard is \(30\text\). The length of the yard is 30 feet, and the width is 20 feet. This is a scenario where the area formula of a rectangle can be applied. Do you have enough sod to cover the entire yard? ![]() Your yard has a length of 25 feet and a width of 30 feet. The rectangle area calculator is an online calculator to find the area, perimeter, and diagonals. You want to determine if this is enough grass to cover the entire yard, so you need to compare the area of the sod to the area of your yard. You want to plant grass in your new backyard, and you currently have 645 square feet of sod available. In this case, our answer would be 640 m 2. Area is the result of multiplying two dimensions, length and width, which can be represented as a power of 2. The units associated with surface area will always be units squared. The area of the rectangle can be calculated by multiplying \(l\times w\), or \(32\times20\), which is 6,400. For example, the rectangle below has a length of 32 meters and a width of 20 meters. An easy to use, free area calculator you can use to calculate the area of shapes like square, rectangle, triangle, circle, parallelogram, trapezoid, ellipse, octagon, and sector of a circle. A represents area, l represents length, and w represents width. When determining the area of a rectangle, the formula \(A=l\times w\) can be applied. Situations such as these will require the use of surface area calculations. Area calculations are made for scenarios such as determining the number of tiles needed to cover the bottom of a swimming pool, the amount of wrapping paper needed to wrap a gift, or the amount of square footage you have in your backyard. All of these are supported by this online area calculator.Calculating surface area is a skill that can be applied in many real-world situations. 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. This calculator useful for students, Engineers and anyone. The formula for the area of a rectangle is width x height, as seen in the figure below: Area of Irregular Quadrilateral is calculated by knowing 4 sides and a angle or diagonal of it. 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. ![]() It will also show the perimeter of the shape. As you add points the area will be updated below and converted into acres, square feet, meter, kilometers and miles. Continue to click along the outside edge of the shape you want to calculate the area of. This is the simplest figure to calculate as all you need is a single measurement. This surface area of a rectangle calculator is the perfect tool for you to calculate the surface area of a rectangle from its length and width. Enter an address or zoom into the map then click on the starting point of your shape. the little squares in each corner mean 'right angle' Each internal angle is 90 Opposite sides are parallel and of equal length (so it is a Parallelogram ). The formula for the area of a square is side 2, as seen in the figure below: A rectangle is a four-sided flat shape where every angle is a right angle (90). 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. 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. 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.
