Answer:

40 inches.

Explanation:

If you want to measure how much fence you need to enclose a rectangle, you have to add up the lengths of all its sides. That's called the perimeter. The easiest way to find it is to use this handy-dandy formula:

Perimeter = 2 (length + width) units

where length and width are how long the rectangle's sides are.

For example, let's say you have a rectangle that is 12 inches long and 8 inches wide. To find its perimeter, you just plug in those numbers into the formula:

Perimeter = 2 (12 + 8) inches

Perimeter = 2 (20) inches

Perimeter = 40 inches

Ta-da! The perimeter of the rectangle is 40 inches.
