Question

a picture is in the shape of a rectangle. it is 5 inches long and 4 inches wide. what is its perimeter? inches

Explanation:

Step1: Recall the formula for the perimeter of a rectangle

The formula for the perimeter \(P\) of a rectangle is \(P = 2\times(\text{length}+\text{width})\).

Step2: Substitute the given values into the formula

Given that the length \(l = 5\) inches and the width \(w = 4\) inches. Then \(P=2\times(5 + 4)\).

Step3: Calculate the sum inside the parentheses first

\(5+4=9\). So \(P = 2\times9\).

Step4: Calculate the final result

\(2\times9 = 18\).

Answer:

\(18\) inches
