A goat is tied to one corner of a square plot of side 12m by a rope 7m long. Find the area it can graze?	Choose the correct choice from the following options: A) 32 B) 36.5 C) 38.5 D) 39 E) 39.5
Area covered by goat = Pi*r^2/4 ( here we divide by 4 because rope is tied at the corner of the plot and only 1/4 part , the goat can graze)   where r= 7 m = length of rope   So area = (22/7)*7*7/4=

<output>77/2 = around 38.5</output>
38.5 sq m   answer :38.5
<result>C</result>
