1050 sq. m.
3850 sq. m.
950 sq. m.
1075 sq. m.
None of these
Solution:
The length of the rope is 35m (70/2).
The area covered by each horse should be equal to the area of sector with radius of 70/2 = 35 m(length of the rope).
Total area covered by the four horses = 4* area of sector of radius 35 metres = Area of circle of radius 35m.
Area left ungrazed by the horses = Area of square field - Area covered by four horses.
= 70² - (22/7) × 35 × 35 = 4900 - 3850 = 1050 sq.m.
