The area of a dog pen is 14 1/5 square feet. The length of the pen is 8 ½ feet. What is the width?
Katen [24]

Answer:

<u>The width is 1.67 or 1 2/3 feet approximately</u>

Step-by-step explanation:

Area of the dog pen = 14 1/5  = 14.2 square feet

Length of the pen = 8 1/2 = 8.5 feet

Width of the pen = x

Let's recall that the formula of the area of a rectangle is:

Area = Length * Width

Replacing with the values we know:

14 1/5 = 8 1/2 * Width

14.2 = 8.5 * Width

Width = 14.2/8.5

Width = 1.67 feet (rounding to the next hundredth)

1.67 ≅ 1 2/3

<u>The width is 1.67 or 1 2/3 feet approximately</u>
