</h3>
Step-by-step explanation:
18 bags of sand will be needed
Perimeter is , or around 63.89 in.
If you meant that the area was 225 in²:
Perimeter is 60 in
#1 = 1/3

Answer:
<h2>The dimensions must all add up to 180°.</h2>
Step-by-step explanation:
For example;
Your triangles' angles are: 56, 77, and 47.
56 + 77 + 47 = 180
*You did not give me any values to solve for, but just since you didn't- I'v provided an example to assist you in doing it yourself. If you want me to solve your full equation please add the angles or 3 dimensions of the triangle.
