Answer:
564 meters
Explanation:
Perimeter is the total length of the sides of the shape.
The formula for finding the perimeter of a rectangle is (length + width) x 2.
(you can also get the same answer by adding the 4 sides of the rectangle, which is length+length+width+width)
Plug in the numbers.
(210 + 72) x2
= 564 meters
