Some other types of quadrilaterals are square, parallelogram, rhombus, trapezium, and kite. Hence, the name itself gives the description of this plane figure.Ī rectangle is a type of quadrilateral. The total measurement of all the interior angles comes out to be 360 degrees.Ī quadrilateral is a combination of two Latin words, where Quadri stands for four, and lateral is described as sides. It is a (four-sided) polygon also known as a tetragon. QuadrilateralĪ quadrilateral is a four-sided plane closed figure. Hence, 42 feet of wire would be required to put a fence around the garden. The answer to this problem can be found by calculating the perimeter of the garden as follows: The length of the garden is 15 feet, and its width is 6 feet. Perimeter of rectangle = length + length + width + widthĬonsider an example of a gardener who wants to find out how much wire would be required to put a fence around his garden. If two adjacent sides of a rectangle are summed up, we get the perimeter of a rectangle, which can be found using the mathematical formula given below, The perimeter of a rectangle is the path or distance covered by the boundary of the rectangle in a 2-dimensional plane. = 840 inch 2 The Perimeter of a Rectangle To figure out the exact area of a rectangle, we use the following formula, The area occupied by rectangular-shaped objects such as a television, blackboard, door, refrigerator, etc., can easily be calculated by utilizing the formula for the area of a rectangle:Ĭonsider an example of a television whose length is 42 inches and width is 20 inches. The area of the rectangle is the entire region surrounded by the rectangle’s boundaries in a 2-dimensional plane. It has 6 faces, 12 edges, and 8 vertices.
