\n Perimeter of a geometric shape is the length of the boundary curve.\r\n Imagine you have to walk along the border of a rectangle or a square until you get back to the same point.\r\n Then the distance travelled is equal to the perimeter of the rectangle or the square.\n
\r\n\n Perimeter \\(R\\) of a rectangle with length \\(L\\) and width \\(W\\) is given as:\r\n $$ R = 2(L+W)$$\n
\r\n\n In a square, the length is the same as the width, i.e., \\(l =w\\).\r\n Thus, substituting \\(L =W\\) in the expression for the perimeter of a rectangle, we can obtain the expression for the perimeter of a square:\r\n $$ S = 2(L+L) = 4L$$\n
\r\n\n In this MagicGraph, you will learn about how to find the perimeter of a rectangular shape.\r\n Shown in the MagicGraph is a rectangular shape with its sides shown in grey.\r\n
\r\n Simply tap on a side to pick it. Once picked, the color of the side turns bright blue, and its length is added to the peripheral length.\r\n
