Final answer:
The perimeter of the rectangular courtyard is 155 feet.
Step-by-step explanation:
To calculate the amount of fencing needed to enclose a rectangular courtyard, you need to find the perimeter of the courtyard. The perimeter is the sum of the lengths of all the sides. In this case, the courtyard is 45.1 feet wide and 32.4 feet long, so the perimeter is:
Perimeter = 2(width) + 2(length)
Perimeter = 2(45.1) + 2(32.4) = 90.2 + 64.8 = 155 feet
Therefore, you will need 155 feet of fencing to enclose your courtyard.
