The expression to find the perimeter of a rectangle is 2(length + width). What is the perimeter, in units, of a rectangle of len

harina [27]

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 $1\frac{2}{7}units$
