Answer:
117.53 feet^2
Step-by-step explanation:
So to start off we need to find the area of the pentagon.
The formula for the area of a pentagon is weird so I’m not going to write it but you can search it up.
So the area would be 27.53 inches^2.
Now for the triangles.
There is 5 triangles in total with a base of 4 and a height of 9.
So the area of one is base*height divided by two.
So it would be 18.
Now we can just multiply 18 by 5 which is 90 feet^2.
So when we add up 90 and 27.53 we get 117.53 feet^2.
Sum of all exterior angles = 360°.
Number of sides = 360 ÷ 40 = 9
Each interior angle = 180 - 40 = 140°.
Answer: <span>The regular polygon has 9 sides and each of its interior angles 140°</span>

Answer:
A) 5 notebooks, 10 pencils
Step-by-step explanation:
n = notebook
p = pencil
1.97n + 1.16p = 21.45
A)✅
1.97(5) + 1.16(10) = 21.45
9.85 + 11.6 = 21.45
21.45 = 21.45
B) ❌
1.97(3) + 1.16(12) = 21.45
5.91 + 13.92 = 21.45
19.83 = 21.45
