Your diagram will show a sector with a side length of 35 metres and an included angle of 140 degrees.
Find the area of a full circle with a radius of 35 metres. You are only watering 140 degrees of a total of 360 degrees in a circle so you are watering of the full circles area.
Area =pi x (r squared)
=
=
=3848 square metres
=1497 square metres
