Question

6 manuel has a garden that is 12 feet long and 9 fe wide. what is the perimeter of manuels garden? use the formula for perimeter, ( p = 2(l + w) ). a. 33 feet b. 42 feet c. 216 feet d. 432 feet

Explanation:

Step1: Substitute the values of \(l\) and \(w\) into the formula

Given \(l = 12\) feet and \(w=9\) feet, substitute into \(P = 2(l + w)\).
So, \(P=2(12 + 9)\).

Step2: Calculate the sum inside the parentheses

First, calculate \(12+9\).
\(12 + 9=21\).
Then the formula becomes \(P = 2\times21\).

Step3: Multiply to find the perimeter

\(2\times21 = 42\).

Answer:

B. \(42\) feet
