Q. The width of a rectangle measures

(1.3 b-1.6)

centimeters, and its length measures

(9.9 b+8.6)

centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?

\newline

-0.6 b+37

\newline

7+11.2 b

\newline

22.4 b+14

\newline

-0.3 b+18.5

Substitute Expressions: The formula for the perimeter $P$ of a rectangle is $P = 2(\text{length} + \text{width})$ . We need to substitute the given expressions for length and width into this formula.
Combine Like Terms: Substitute the given expressions for length and width into the perimeter formula: $P = 2((1.3b - 1.6) + (9.9b + 8.6))$ .
Simplify Terms: Combine like terms inside the parentheses: $P = 2((1.3b + 9.9b) + (-1.6 + 8.6))$ .
Distribute $2$ : Simplify the terms inside the parentheses: $P = 2((11.2b) + (7))$ .
Perform Multiplication: Distribute the $2$ across the terms inside the parentheses: $P = 2 \times 11.2b + 2 \times 7$ .
Perform Multiplication: Distribute the $2$ across the terms inside the parentheses: $P = 2 \times 11.2b + 2 \times 7$ .Perform the multiplication: $P = 22.4b + 14$ .
