Answer:

OPTION B

1\frac{2}{7}units

Step-by-step explanation:

1. You have the following formula for calculate the perimeter of a rectangle:

P=2(l+w)

Where l is the lenght and w i the width.

2. Therefore, if the rectangle has the following dimensions:

l=\frac{1}{7}units\\\\w=\frac{1}{2}units

You can substitute these values into the formula shown above to calculate the perimeter of a rectangle. Therefore, you obtain the following result:

P=2(\frac{1}{7}units+\frac{1}{2}units)=\frac{9}{7}units or 1\frac{2}{7}units
