Area of grazed plot = area of 3 sectors 

ropes lenght
 = 7m

= (theta 1/360)(22/7)r^2 +(theta2/360)(22 / 7)r^2+(theta 3/360)(22 / 7)r^2
={ (22/7)(7)(7)[theta 1 + theta 2 + theta 3] } / 360
= (154 / 360)(180)
= 77 cm2
0
it is not an equilateral triangle so theta should not be 60
its 360
I haven't got
