Answer:
50 meters
Explanation:
Perimeter is the sum of all the sides. Since a rectangle has 4 sides, that means that there are 2 length sides and 2 width sides.
First, we need to see how long the width sides are when they are added together. Since the pen is a rectangle, they will be the same length.
30+30=60
Now, we subtract that from the total perimeter.
160-60=100
We are left with 100 meters, but that represents both length sides. To find the length of one side, we must divide 100 by 2.
100/2=50 meters
