Question

Tina decided to build a pen for her new puppy. She decided the length of the pen would be 7 feet and the width would be 4 2/3 feet. What will be the perimeter of the new pen?

Answer 1

The perimeter of the object is
`23.\overline3` feet.

Explanation:

The perimeter of an object is solved with the formula:

`\bullet \ \ \ 2l + 2w = p`,

where p is the perimeter of the object, l is the length of the object, and w is the width of the object.

Therefore, we want to define the values we have been given:

• 7 feet - length (l )
• 4 2/3 feet - width (w )

We can use these and supply them into the equation to solve for p.

`\displaystyle 2(7) + 2(4(2)/(3))=p\\\\14 + (20)/(3) = p\\\\p = (70)/(3)`

Therefore, the perimeter of the object is
`\displaystyle (70)/(3)` or
`23.\overline{3}` feet.
