1/23/2024 0 Comments Diagonal of a rectangle are![]() ![]() From the figure we can see that AC and BD are the diagonals of the rectangle ABCD. Thereby, the diagonal of a big wall is 14.03 meters.We know that a rectangle has 2 diagonals. 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. ![]() ![]()
