In rectangle ABCD, side BC is 4.3 cm larger than side AB Find the sides of the rectangle if the perimeter is 29.6 cm.

1. According to the condition of the problem AB = BC – 4.3 centimeters.

2. Using the formula for calculating the perimeter of a rectangle, we calculate its sides:

2 (BC – 4.3) + 2BC = 29.6;

2BC – 8.6 + 2BC = 29.6;

4BC = 29.6 + 8.6 = 38.2;

BC = 38.2 / 4 = 9.55 centimeters.

AB = 9.55 – 4.3 = 5.25 centimeters.

Answer: side AB of rectangle ABCD is 5.25 centimeters, side BC is 9.55 centimeters.
