The dimensions given when you have a triangle is the base and height of the triangle. The formula for the area is
A = 0.5bh
The unknown here is h. We can determine that from the cost of mulch that covers the whole area of the triangle. The equation would be:
4A = 33
Substituting A = 0.5*5.5*h = 2.75h to the equation:
4(2.75h) = 33
11h = 33
h = 33/11
h = 3 feet
The answer is 8/5 which also matches quizlet
Answer:

Step-by-step explanation:
This is basic trigonometry.




And finally perimeter (p):

Answer: 1080</h3>
====================================================
Explanation:
We have an octagon because there are n = 8 sides. The diagram below shows one way to number the sides so you can count them efficiently (without missing any or double counting any).
----------------
Plug n = 8 into the formula below
S = 180(n-2)
S = 180(8-2)
S = 180(6)
S = 1080
The 8 interior angles add up to 1080 degrees.
Answer:
The area of Blanket A is 18yd^2
