Answer:
Step-by-step explanation:
<u>Use formula:</u>
- A = 1/2 Pa, where P-perimeter of the polygon, a- apothem
1)
- A = 1/2(7*13.9)(14.4) = 700.56 ≈ 700.6
Correct choice is B
2)
Correct choice is A
True because it is used to collect information on data tables and other things.
Answer:
-12
Step-by-step explanation:
We start with the equation: 
Substitute the variables: 
Solve using order of operations (start with multiplication): 
And then addition/subtration: 
Let's call the width: w
the lenght is then 3w+4 ("4 more than 3 times the width")
and the parameter would be 2(w+3w+4), that is 2*(4w+4), that is 8w+8.
this is also equal to 18.4:
8w+8=18.4
8w=10.4
w=1.3
this is the width, and the lenght is:
4+3*1,3=4+3.9=7.9
and the area is their product:
1.3*7.9=10.27
