Answer:
<h2>2,268 square units</h2>
Step-by-step explanation:
Step 1
Find the area of 1 Triangle
To find this, we will use this formula:

Let's use the formula!

<em>The area of 1 triangle is 189 square units</em>
<em></em>
Step 2
Find the area of the whole intire shape by multiplying the area of 1 triangle with the amount of sides.
There are 12 sides, so let's multiply 189 by 12
189x12=2268
<h2>
Hence, the area of the regular polygon is 2,268 square units</h2>
1.) a>10
2.) a<3.5
How I got it: 1.) Subtract 3 from both sides, leaving -2a<10.
2.) Divide by -2 from both sides, remember to flip the inequality sign when dealing with negatives. This leaves you with a>10.
For number 2.) I divided both sides by 5, leaving a<3.5, though this answer may be wrong.
M is always positive is not true.
Hope this helps!
