Question

what is the perimeter in feet of this rectangle if a side measures 11 feet and another side measures 30 feet (note that you do not need to enter \feet\ in the answer, only the number)?

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 \(l = 30\) and \(w = 11\), we substitute into the formula: \(P=2(30 + 11)\).
First, calculate the sum inside the parentheses: \(30+11 = 41\).
Then, multiply by 2: \(2\times41=82\).

Answer:

82
