Answer:

OPTION B


1(2)/(7)units

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=(1)/(7)units\\\\w=(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((1)/(7)units+(1)/(2)units)=(9)/(7)units or
1(2)/(7)units
