Steve is turning half of his backyard into a chicken pen. His backyard is a 242424 meter by 454545 meter rectangle. He wants to put a chicken wire fence that stretches diagonally from one corner to the opposite corner.
The rectangle measures, 24 m by 45 m Therefore, to get the diagonal we use the Pythagoras theorem a²+b²=c², then = √24²+45² = √2601 = 51 Therefore, Steve will need 51+24+45 = 120 meters
