![]() ![]() Want to change the area unit? Simply click on the unit name, and a drop-down list will appear. By default, the first two parameters set the location. Step 3: Write the answer in respective square units. Step 2: Calculate the product of the length and breadth of the rectangle. Following are the steps that help calculate the area of the rectangle, Step 1: Note down the dimensions of the rectangle. If the height and width are in cm, the area is shown in cm. A rectangle is a four-sided shape with every angle at ninety degrees. The area of the rectangle is defined as the product of its length and breadth. Regular polygon area formula: A = n × a² × cot(π/n) / 4 To work out the area of a square or rectangle, multiply its height by its width.We know that the area of a rectangle can be calculated by its length multiplied by its width. The length of the given rectangle is 14 cm, and its width is 10 cm. Quadrilateral area formula: A = 1/2 × e × f × sin(angle) The properties of a rectangle can be used to calculate the area of a rectangle.Octagon area formula: A = 2 × (1 + √2) × a².Area and perimeter help us measure the size of 2D shapes. From there, we’ll tackle trickier shapes, such as triangles and circles. Hexagon area formula: A = 3/2 × √3 × a² We’ll start with the area and perimeter of rectangles.Trapezoid area formula: A = (a + b) × h / 2.Circle sector area formula: A = r² × angle / 2. ![]() ![]() For the sake of clarity, we'll list the equations only - their images, explanations and derivations may be found in the separate paragraphs below (and also in tools dedicated to each specific shape).Īre you ready? Here are the most important and useful area formulas for sixteen geometric shapes: Well, of course, it depends on the shape! Below you'll find formulas for all sixteen shapes featured in our area calculator. ![]()
