Answer:
12x-15
Step-by-step explanation:
A triangle has 3 sides
An equilateral triangle has 3 sides that are all the same length
The perimeter of a triangle is
P = s1+s2+s3
P = 4x-4 + 4x-5+4x-5
Combine like terms
P = 12x -15
For AD to be parallel 2x+4º should be equal to 79º
2(37)+4 = 78º
78º<79º
Since they aren't equal the lines are not parallel to each other.
Answer: 819.73 yd²
<u>Step-by-step explanation:</u>

= 
= 
= 29 * 30
= 870

= π(4)²
= 16π
≈ 50.27
Area of the park = 
= 870 - 50.27
= 819.73
