The width of the rectangle is 40.5 m and the length is 5/3 of the width. Find the perimeter of this rectangle.

First of all, let us determine what the length of this rectangle is equal to, if, according to the condition of the problem, it is 5/3 of the width, equal to 40.5 m.Thus, we get:

40.5 * 5/3 = 67.5 (cm).

In order to find the perimeter of a given rectangle, we need to calculate the sum of its two known sides, and then double the resulting result. So, let’s find the perimeter of the rectangle:

P = 2 (40.5 + 67.5) = 216 (cm).

Answer: The perimeter of the original rectangle is 216 cm.
