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

Answer:

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

Step-by-step 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.

$\displaystyle 2(7) + 2(4\frac{2}{3})=p\\\\14 + \frac{20}{3} = p\\\\p = \frac{70}{3}$

Therefore, the perimeter of the object is $\displaystyle \frac{70}{3}$ or $23.\overline{3}$ feet.
