![]() In this case, our answer would be 640 m 2. Area is the result of multiplying two dimensions, length and width, which can be represented as a power of 2. The units associated with surface area will always be units squared. 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. When determining the area of a rectangle, the formula \(A=l\times w\) can be applied. Situations such as these will require the use of surface area calculations. Area calculations are made for scenarios such as determining the number of tiles needed to cover the bottom of a swimming pool, the amount of wrapping paper needed to wrap a gift, or the amount of square footage you have in your backyard. The surface of a sphere in Euclidean solid geometry is a non-Euclidean surface in the sense of elliptic geometry.Calculating surface area is a skill that can be applied in many real-world situations. In spherical geometry, a spherical rectangle is a figure whose four edges are great circle arcs which meet at equal angles greater than 90°. This example shows 4 blue edges of the rectangle, and two green diagonals, all being diagonal of the cuboid rectangular faces. ![]()
