When it is said that one value is a certain number of times greater or less than another, it is necessary to perform division.
Let’s find the width of the rectangle, provided that it is 2 times less than its length, equal to 8 cm:
8: 2 = 4 cm.
The area of such a figure corresponds to the formula:
S = a * b = 8 * 4 = 32 cm².
The perimeter is the sum of all sides and is calculated using the formula:
P = 2a + 2b = 2 * 8 + 2 * 4 = 16 + 8 = 24 cm.
