Question

the face of a cell phone measures 4.55 inches by 2.6 inches. find the perimeter of the rectangular face. the perimeter of the rectangular face is (type an integer or a decimal.)

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. Here, \(l = 4.55\) inches and \(w=2.6\) inches.

Step2: Substitute the values into the formula

First, find the sum of the length and the width: \(l + w=4.55 + 2.6=7.15\) inches.
Then, multiply the sum by 2: \(P = 2\times7.15\).

Step3: Calculate the result

\(2\times7.15 = 14.3\) inches.

Answer:

\(14.3\)
