Square geometry is one way to understand the arithmetic square operation (raising a number to the 2-nd power), as well as square roots.Īnother way to think about the square is as a special case of a rhombus - a geometrical figure with equal sides and opposite equal angles, a kite (two pairs of adjacent equal angles), a trapezoid (one pair of opposite sides are parallel), a parallelogram (all opposite sides are parallel), and, of course, a rectangle, in which opposite sides are equal and has only right angles. The simplicity of the square is why it is usually one of the first figures geometry students get familiarized with, but in reality, we rarely deal with square objects. Multiply 6 km and 4 km Area 24.0 km 2 Area of Rectangle 6 km by 4 km is 24.0 km 2 Area & Perimeter of a Rectangle Calculations Here are examples of Area of Rectangle calculations. Name: ExtentCreation.py Import system modules import arcpy Set environment settings r'C:dataCity. Get the extent rectangle of each feature. Square Kilometers The area unit will be square kilometers. The perimeter of a square is one of the easiest to calculate in that it requires just one measurement of the square to be known - its side:įrom this one measurement, one just needs to multiply it by 4 to get to the perimeter, so the formula used in this perimeter of a square calculator is quite simple. Specifies the unit that will be used to calculate area. How to calculate the perimeter of a square? Use this calculator to easily calculate the area of a rectangle given its sides (length and width) in any metric: mm, cm, meters, km, inches, feet, yards, miles. This is the formula used in our perimeter of a square online calculator. Rectangle calculator is a tool with the help of which you can calculate the area of a rectangle, the diagonal of a rectangle and the perimeter of a rectangle. The formula is: side x 4 and the result will be in whatever metric you did the measurement in: mm, cm, dm, meters or in, ft, yards, etc. In a rectangle, because a diagonal bisects the rectangle into two congruent triangles, those two triangles will also be congruent to each other. square kilometre (sq km) 1,000,000 m square megametre (sq Mm) 1 x. Example: find the perimeter of a square This tool will calculate the area of a rectangle from the dimensions of length.You can notice that for a trapezoid with a b (and hence c d h), the formula gets simplified to A a × h, which is exactly. Substitute these values into the trapezoid area formula: A (a + b) × h / 2. Whereas the basic formula for the area of a rectangular shape is length × width, the basic. To find the area of a trapezoid ( A ), follow these steps: Find the length of each base ( a and b ). ![]() ![]() How to calculate the perimeter of a square? Learn how to measure and calculate the volume of a solid.Let's start with the trigonometric triangle area formula:Īrea = (1/2) × a × b × sin(γ), where γ is the angle between the sides. Substituting h into the first area formula, we obtain the equation for the equilateral triangle area: ![]() Usage Caution: This tool modifies the input data. One leg of that right triangle is equal to height, another leg is half of the side, and the hypotenuse is the equilateral triangle side.Īfter simple transformations, we get a formula for the height of the equilateral triangle: Adds information to a feature's attribute fields representing the spatial or geometric characteristics and location of each feature, such as length or area and x-, y-, z-coordinates, and m-values. Works with imperial and metric units: mm, cm, meters, km, inches, feet, yards, miles, and more. See our right triangle calculator to learn more about right triangles. Perimeter of a rectangle calculator online - easily calculate the perimeter of any rectangle, given its length and width. Height of the equilateral triangle is derived by splitting the equilateral triangle into two right triangles. Use this calculator to easily calculate the area of a circle, given its radius in any metric: mm, cm, meters, km, inches, feet, yards, miles, etc. The basic formula for triangle area is side a (base) times the height h, divided by 2: H = a × √3 / 2, where a is a side of the triangle.īut do you know where the formulas come from? You can find them in at least two ways: deriving from the Pythagorean theorem (discussed in our Pythagorean theorem calculator) or using trigonometry. The formula for a regular triangle area is equal to the squared side times the square root of 3 divided by 4:Īnd the equation for the height of an equilateral triangle looks as follows: ![]()
