Surface Area Of Rectangle Formula
Surface Area Of Rectangle Formula
The Surface Area Of Rectangle Formula in geometry refers to the area that a rectangle occupies on a two-dimensional plane. A rectangle is a quadrilateral that has a two-dimensional geometry with four sides and four vertices. The rectangle’s four angles are all right angles or exactly 90 degrees. The opposing sides of the rectangle are equal and parallel. It should be noted that a parallelogram likewise has equal and parallel opposite sides, but the angles are not exactly 90 degrees. Every figure in two dimensions has a length and a width. It is measured in square units like square millimetres and square metres, among others. The surface area of a solid item is a measurement of the total space that the surface of the thing occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more complicated than the definition of arc length for one-dimensional curves or the definition of surface area for polyhedra (i.e., objects with flat polygonal faces), where the surface area is equal to the sum of the areas of its faces. When smooth surfaces, like spheres, are represented as parametric surfaces, their surface area can be calculated. This definition of surface area, based on infinitesimal calculus methods, uses partial derivatives and double integration.
How to find the surface area of a rectangle?
The dimensions of a rectangle determine the Surface Area Of Rectangle Formula. In essence, the Surface Area Of Rectangle Formula is equal to the product of its length and breadth. In contrast, the perimeter of a rectangle is equal to the summation of its four sides. Consequently, one can say that the Surface Area Of Rectangle Formula equals the space enclosed by its perimeter. But in the case of a square, whose sides are all equal, its area will be equal to the square of side length. The area of a rectangle can be calculated using the following Surface Area Of Rectangle Formula.
Step 1: Multiply the width by the length.
Step 2: L X W, where L and W stand for length and width, respectively.
