Question

thomas wants to put a fence around a rectangular garden that is 12 feet long and 7 feet wide. how much fencing he will need? 84 feet 49 feet 28 feet 38 feet

Explanation:

Step1: Recall the formula for the perimeter of a rectangle

The formula for the perimeter \(P\) of a rectangle is \(P = 2(l + w)\), where \(l\) is the length and \(w\) is the width.

Step2: Substitute the given values into the formula

Given \(l = 12\) feet and \(w = 7\) feet. Then \(P=2(12 + 7)\).
First, calculate the sum inside the parentheses: \(12+7=19\).
Then, multiply by 2: \(2\times19 = 38\).

Answer:

38 feet
