Question

four horses r tied with equal rops at 4 corners of square field of side 70m sothat they can just reach one another​

Answer 1

Area of square = 70*70= 4900sqm

horses can just reach 1 other implies radius of circle is half the side i.e 35m

total area 1 horse can cover =22/7(35*35)=3850sqm

area that a horse can cover on the field is only 90degrees of the circle so area will be 1/4(3850)sqm

total area covered inside grazing area by 4 horses = 4(1/4(3850))= 3850sqm

so total area left ungrazed = 4900-3850= 1050sqm
