You can put this solution on YOUR website! Hi there,
140/360 = length of arc/pi x diameter
140/360 = length of arc/ pi x 160
length of arc = (140 x 160)/360
length of arc = 62.22 ft (2 decimal places)
Perimeter of field = 62.22 + 80 + 80 = 222.22 ft.
140/360 = Area of sector/pi x radius^2
140/360 = Area of sector/pi x 80^2
(140 x 80^2)/360 = area of sector
area of sector = 2488.89 ft^2 (2 decimal places)
Perimeter of plot = 222.22 ft.
Area of plot = 2488.89 ft^2
Hope this helps :-)

The other person is WRONG! Perimeter:, with D being the diameter Area:, with r being the radius.
Calculate those!!
