Four cows are tied with a rope of 7 cm at four corners of a quadrilateral field of unequal sides. Find the total area grazed.
area grazed = area of the sectors.
let the angles be angle x, angle y, angle w, angle z
area grazed = pi/360 X r2( angle x + angle y + angle w,+ angle z)
since angles in a quadrilateral add upto 360, angle x + angle y + angle w,+ angle z= 360
area grazed = 22/7 X 7 X7 360/360
area grazed = 154 m2
hope this helps
