Answer:
83.4
Step-by-step explanation:
Area of a Regular Polygon: L (of side) times apothem (height) x 1/2
L : 13.9
Looking at the triangle we can assume the height would be 12 since its logical that 3 of the 4 lines can fit in the middle of the triangle.
H: 12
13.9 x 12 = 166.8
166.8/2 = 83.4
In my opinion I think that you have to multiply 13.55 by 8 ounces to find how much she needs to pay.
2x + 7y + 3x + 5y
5x + 12y
2.10 is the answer to the nearest 10th
