Want to change the area unit? Simply click on the unit name, and a drop-down list will appear. Example 4: Find the area of the right-angled triangle with base and height 5cm and 8 cm respectively. Solution: Area of rectangle l × b where l and b are length and breadth of rectangle. Regular polygon area formula: A = n × a² × cot(π/n) / 4 Example 3: Find the area of the rectangle with length and breadth 9cm and 3 cm respectively.What is the total distance that Sam covered Solution: The given dimensions of the rectangular park are 60 feet in width and 85 feet in length. He covered 7 rounds of this rectangular park. Example 2: Sam walked around a rectangular park of 60 feet in width and 85 feet in length. Quadrilateral area formula: A = 1/2 × e × f × sin(angle) So, the area of the rectangle is 1470 square centimeters. Finally, we print the value of this variable using a print statement. 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. A represents area, l represents length, and w represents width. The function calculates the area of the rectangle and returns the result, which we store in the area variable. When determining the area of a rectangle, the formula \(Al\times w\) can be applied. Octagon area formula: A = 2 × (1 + √2) × a² In this example, we define the values for length and width, and then we call the calculatearea function, passing in these values as arguments.Hexagon area formula: A = 3/2 × √3 × a².the little squares in each corner mean 'right angle'. Pentagon area formula: A = a² × √(25 + 10√5) / 4 (Jump to Area of a Rectangle or Perimeter of a Rectangle) A rectangle is a four-sided flat shape where every angle is a right angle (90).
