To find how much fencing Jordana will need you will find the perimeter of the given shape. This includes 3 straight sides and a rounded side.
28 ft + 14 ft + 28 ft = 70 feet for the straight sides.
To find the distance around the circular side, you will need to find half of the circumference of the circle.
1/2 x pi x d
1/2 x 22/7 x 14 = 22 feet
70 feet + 22 feet = 92 feet
Jordana will need 92 feet of fencing to enclose this space.
