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>
Answer:
50
Step-by-step explanation:
34%=34/100
34/100 = 17/50
We need to account for both x values on either side of the length, and width.
Thus, the length becomes 10 + x + x = 10 + 2x
and the width becomes 5 + x + x = 5 + 2x
For the second question, I'm assuming we don't account for the area that is covered by the garden.
Then we can say that the path is measured by: (5 + 2x)(10 + 2x) - 50, which is the area of the garden itself.
(5 + 2x)(10 + 2x) - 50 = 54
Expanding the brackets:
x = -9, or x = 3/2
Since x > 0, then x ≠ -9
Thus, the only x-value we can take is x = 3/2
