Grass left will be ./
area of square having side length 70m – area of circle having radius 35m
$4900 - \frac{22}{7} \times 35 \times 35 \\ 4900 - 22 \times 35 \times 5 \\ 4900 - 110 \times 35 \\ 4900 - 3850 \\ 1050 \:$

abhinav821: how radius is 35 m

RAJPUTANALIONS: given E is the midpoint

abhinav821: but e is 70 m

RAJPUTANALIONS: and cows are consuming the grass wth constant time and same amount..

RAJPUTANALIONS: then half of the 70 will be 35

abhinav821: ok this question has come from nguru held in our school but no answer was 1050

RAJPUTANALIONS: answer will be 1050
