Split it into 7 triangles. Half-base of each is 2 so distance of centre to mid point of base is (Pythagoras) square root of (4.62 - 22) = 4.162 So area of each triangle is this times 2, and with 7 triangles multiply also by 7 to get an approximate area of 58 sq in.

How do you find the volume of a heptagon?
The volume of a heptagon can be found in two ways. Multiply the side length by 7/4 and then by the cotangent of a 25 5/7 angle. From the perimeter, measure the distance from the center of the middle of each side. The multiply it by two and then divide by two.

How do you find the area of a heptagon?
The following two methods can find the area of a regular heptagon. These methods will not work on an irregular heptagon. Multiply the length of one side by 7/4 and then by the cotangent of a 25 5/7 degree angle. Multiply the perimeter by the distance from the center to the middle of a side, then divide by two. You must know the length of a side to calculate the area of a heptagon. Area = n (s/2)^2 / tan( pi /n) where n=7; s=side length A septagon is a seven sided figure. Given a regular septagon (with seven sides of equal length), the formula for the area is 7/4 (a^2) * cot (180 degrees/7), where a is the length of one side.
