In order to find the part of an integer value, you must divide it by the denominator of the fraction and multiply by its numerator.
Determine the width of the rectangle, provided that it is 3/7 of its length, equal to 14 cm:
b = 14: 7 * 2 = 2 * 2 = 4 cm.
The perimeter is calculated using the formula:
P = 2a + 2b = 2 * 14 + 2 * 4 = 28 + 8 = 36 cm.
The area corresponds to:
S = a * b = 14 * 4 = 56 cm².
