Question

find the perimeter.
9 in
7 in
p = ? in

Explanation:

Step1: Recall the formula for the perimeter of a rectangle

The formula for the perimeter \( P \) of a rectangle is \( P = 2\times(\text{length}+\text{width}) \). Let the length \( l = 9\) in and the width \( w=7\) in.

Step2: Substitute the values into the formula

Substitute \( l = 9\) and \( w = 7\) into \( P = 2\times(l + w)\). So \( P=2\times(9 + 7)\).
First, calculate the sum inside the parentheses: \(9+7 = 16\). Then multiply by 2: \(P=2\times16\).

Answer:

\(32\)
