+129852 We have two triangles each with a base of 7.7m and a height of 7.0 m
Their total area = 7 * 7.7 = 53.9 m^2
And we have two rectangles with dimensions of 8 * 18
Their total area = 2 * 18 * 8 = 288 m^2
Finally we have a 7.7 by 18 rectangle in the center = 7.7 * 18 = 138.6 m^2
Area = [ 53.9 + 288 + 138.6 ] = 480.5 m^2
