Note: figure not drawn to scale.
The playing area of a certain outdoor game requires markings according to the figure shown. The ratio of AB;BC:AC is 3:4:5; O is the midpoint of the circle, R and Q are both points on the circle with center O and corners of square OBQR. If QB is 1/3 of AB and a person running in a straight line from Q to R travels 3√2 meters, approximately how many meters of paint are required to paint the playing area on a surface (assume the lines have negligible width)?
A. 54Ï€
B. 97
C. 72
D. 67
E. 45
The OA is D.
I don't have clear this PS question. Is there a strategic approach to solve it? Can any experts help, please? Thanks!
