The perimeter is a linear measure and has units as meters, centimeters. In that case, you would use the formula: perimeter 2 × length plus 2 × width. If you dont have the area, you can use the rectangles perimeter instead. Just plug the area and length of the rectangle into the formula and solve for the width. The units are in place to give an indication of the order of the calculated results such as ft, ft 2 or ft 3. We can write the perimeter of the rectangle as twice the sum of its length and width. To find the width of a rectangle, use the formula: area length × width. Example 1: Rectangle has the length 13 cm and width 8. Length (in meter) X Width (in meter) X Height (in meter) Cubic meter (m3) We can define dimensions in Meter, Centimeter, Inch. substituting by the above equation we get. A rectangle has two diagonals, they are equal in length and intersect in the middle. The perimeter of a rectangle is the total length of all the four sides. l 2w, l 2 w, Now you know that the area of a rectangle is lengthwidth so you can write. in order to express l l in terms of w w, i.e. The formula for the perimeter, 'P' of a rectangle whose length and width are 'l' and 'w' respectively is P 2 (l + w). If you do, then the formula for the rectangle's area was used to figure out how much paint and floor covering was needed. the width of the rectangle is half the length. Units: Note that units of length are shown for convenience. The formula for the area, 'A' of a rectangle whose length and width are 'l' and 'w' respectively is the product of length and width, that is, 'A l × w'. Use this calculator if you know 2 values for the rectangle, including 1 side length, along with area, perimeter or diagonals and you can calculate the other 3 rectangle variables.Ī square calculator is a special case of the rectangle where the lengths of a and b are equal.
