Side AB of the quadrangle ABCD is equal to the side of the square, the perimeter of which is 24 cm. Side CD is 4 cm more than AB and 3 cm less than CB. Side AD is 20 mm. more than the sum of the sides AB and CD. Find the perimeter of the quadrangle.

1. Determine the length of the side of the rectangle AB:

24: 4 = 6 cm;

2. Determine the length of the side of the СD quadrangle:

6 + 4 = 10 cm;

3. Determine the length of the side of the quadrangle CB:

10 + 3 = 13 cm;

4. Determine the sum of the sides of the quadrangle AB and СD:

6 + 10 = 16 cm;

5. Determine the length of the side of the blood pressure quadrilateral:

16 cm + 20 mm = 16 cm + 2 cm = 18 cm;

6. Determine the perimeter of the quadrangle:

6 + 10 + 13 + 18 = 47 cm.

Answer: The perimeter of this quadrangle will be 47 centimeters.
