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
