![]() Solve the above equation for L and find W using W = P / 2 - L. Rewrite as a standard quadratic equation in L Find W and L in terms of P and A.Īnd W by P / 2 - L in A = W * L to obtain Let W and L be, respectively, the width and length of the rectangle. Let P be the perimeter of a rectangle and A its area. There are conditions under which this problem has a solution (see formulation of problem below). The outputs are the width, length and diagonal of the rectangle. Thereby, the diagonal of a big wall is 14.03 meters.Then these equations are solved for L and W which are the length and width of the rectangle.Įnter the perimeter P and area A as positive real numbers and press "enter". What is the diagonal of a big wall having a length of 14 meters and a width of 1 meter?Īs per the known properties of a rectangle, the formula for calculating the diagonal length is:ĭiagonal (d) of a big wall = \(\sqrt\) Therefore, the area of a brick is 171 square centimeters.Įxample 3. Find the area of brick having a length of 19 centimeters and a width of 9 centimeters?Īs per the known properties of a rectangle, the formula for calculating the area of a rectangle is: Thereby, the perimeter of the TV screen is 160 inches.Įxample 2. Find the perimeter of a TV Screen whose sides are 45 inches and 35 inches?Īs per the known properties of a rectangle, the formula for calculating the perimeter of a rectangle is: As a result, the length of the diagonal will be:Įxample 1. The diagonal is the hypotenuse of the right triangle. The rectangle’s length and width, that is l and w, represent the base and height of the right triangle respectively. Let ‘d’ be the diagonal of the rectangle. In the figure below, diagonal AC divides the rectangle into two right triangles – \(\Delta\)ABC and \(\Delta\)ADC. Each diagonal divides the rectangle into 2 right triangles. A rectangle has two diagonals of equal length that bisect each other. The formula for calculating the area of a rectangle is:Īrea of a rectangle, A = Length × width or l × wģ. The area of a rectangle equals the product of the length and width. The amount of space covered by a two-dimensional shape in a plane is called its area. If its length is l and its width is w, then,Ģ. It is measured in the same units as its sides. The perimeter of a rectangle is defined as the measure of the boundary of the rectangle. If the length of the rectangle is l and the width is w then,ġ. Opposite sides are equal AB = DC, AD = BCĭiagonal bisect each other AO = OC, DO = OBĪll interior angles are equal to 90\(^\circ\). Let us take rectangle ABCD as the reference rectangle. ![]() Similarly, the width of a rectangle is equal to the circumference of the circular base or top of the cylinder. The height of the cylinder is equal to the length of the rectangle in this case. When the rectangle is rotated along the line connecting the midpoints of the shorter parallel sides, it forms a cylinder.In addition, the circumference of the circular base or top of the cylinder is equal to the length of a rectangle. The height of the cylinder is equal to the width of the rectangle in this case. When the rectangle is rotated along the line connecting the midpoints of the longer parallel sides, it forms a cylinder.The rectangle is known as a square if the two diagonals bisect each other at right angles.The diagonals of a rectangle bisect each other at two different angles- one acute angle and one obtuse angle.The sum of all interior angles of a rectangle is 360 degrees.A rectangle is a four-right-angle parallelogram.The area of a rectangle is equal to the product of its length and width.The perimeter of a rectangle is equal to the sum of the measure of its sides.The diagonals of a rectangle cut each other in half.The opposite sides of a rectangle are equal and parallel.All angles of a rectangle measure 90 degrees.A rectangle has four sides and four vertices.The properties of a rectangle are based on its side lengths, angles and diagonals.
