Answer:
92 ft
Step-by-step explanation:
Assume the garden has the shape shown below.
The length of fencing equals the distance around three sides of the rectangle plus that around the semicircle.
1. Around the rectangle
Distance = 28 ft + 14 ft + 28 ft = 70 ft
2. Around the semicircle
For a circle.
C = 2πr
For the semicircle,
½C =½(2πr) = πr
D = 14 ft, so
r = 7 ft

3. Total distance
Distance = 70 ft + 22 ft = 92 ft
Jordan will need 92 ft of fencing.

Permutation
504 ways
Step-by-step explanation:
The difference between combinations and permutations is ordering. With permutations we DO care about the order of the elements, whereas with combinations we don't.
In your graphing calculator, type
nPr(9,3)
(9 letters in trapezoid, 3 letter combos)
and it returns 504.
