**Reiny**, Tuesday, November 6, 2012 at 11:04amif the perimeter of the heptagon (7 sides) is appr 44.1 ,then each side is appr 6.3

look at one of the 7 equal isosceles triangles that can be formed

area of one of those = (1/2)(6.3)(6.5) = 20.475

so the area of the heptagon is 7(20.475) = 143.325

or

appr 143.3
