The length of the rectangle is 6 1/4 cm. The width is 1 2/3 times shorter than the length. Find the perimeter of the rectangle.

First, let’s find how many centimeters make up the width of a given rectangular quadrangle.

In the initial data for this task it is reported that the length of this rectangular quadrangle is six and a quarter centimeters, and the width of this quadrangle is one and two-thirds times shorter than its length, therefore, the width of this rectangular quadrangle is:

(6 + 1/4) / (1 + 2/3) = (25/4) / (5/3) = (25/4) * (3/5) = (25/5) * (3/4 ) = 5 * (3/4) = 15/4 cm.

Find the perimeter of this rectangular quadrangle:

2 * (25/4 + 15/4) = 2 * 40/4 = 2 * 10 = 20 cm.

Answer: 20 cm.
