| **The length of the rectangle is one whole 4/20 meters and the width is 3/20 meters less than the length. find the perimeter of the rectangle.**

The task:

length of rectangle a – 1 4/20 meters,

the width of the rectangle b -?, 3/20 meters less than the length,

the perimeter of the rectangle P -? meters.

Solution:

1) calculate the width of the rectangle b:

b = a – 3/20 = 1 4/20 – 3/20 = 24/20 – 3/20 = 21/20 meters;

2) define the perimeter of the rectangle:

P = (a + b) 2 = (1 4/20 + 21/20) 2 = (24/20 + 21/20) 2 = (45/20) 2 = 90/20 = 9/2 = 4 1/2 meters.

Answer: the perimeter of the rectangle is P = 4 whole 1/2 meters.
