Two 2 1/2 inch plastic strips and two 5 1/3 inch plastic strips are used to form a rectangle. What is the perimeter of the rectangle?

Verified Answer :

Answer

The perimeter of the rectangle is \(15\frac{2}{3}\)

Explanation

To solve this, we are going to use the formula for the perimeter of a rectangle:

\(P=2(w+l)\)

where

\(P\) is the perimeter of the rectangle

\(w\) is the width of the rectangle

\(l\) is the length of the rectangle

We can infer from our problem the the shorter strips are \(2\frac{1}{2}\) inches, so \(w=2\frac{1}{2}\). That leaves us with \(l=5\frac{1}{3}\). Let's replace those values in our formula to find \(P\):

\(P=2(w+l)\)

\(P=2(2\frac{1}{2}+5\frac{1}{3})\)

\(P=2(\frac{5}{2} +\frac{16}{3} )\)

\(P=2(\frac{47}{6} )\)

\(P=\frac{47}{3}\)

\(P=15\frac{2}{3}\)
