Question 1:
A man walking at the rate of 6km per hour crosses a square field diagonally in 9 seconds the area of the field is
A.110 sq.m
B.111.5 sq.m
C.112.5 sq.m
FeedbackDistance covered in 9 seconds = (6×1000/3600)×9 = 15m Diagonal of square field = 15m Side of square =a then diagonal of that square= Root of 2 a Hence area of the square = a^2= (15^2)/2 =112.5 sq.m
D.114 sq.m
