The first thing we must do in this case is to calculate the area of the patio. We have then that: A = (7.5) * (9) = 67.5 feet ^ 2. Then, we calculate the area of each stone: Ap = (6) * (6) = 36in ^ 2 We make the conversion to feet: Ap = (36) (in ^ 2) * (1/12) ^ 2 (foot / inches) ^ 2 Ap = 0.25 feet ^ 2 Finally we have that the area covered by all the stones is: (0.25) * (275) = 68.75 feet ^ 2 We observed that: 68.75 feet ^ 2> 67.5 feet ^ 2 Answer: there are enough stones to cover the patio 68.75 feet ^ 2> 67.5 feet ^ 2
Since 111 is greater than 33, I will assume that you meant 11 votes for a candidate. Also, assuming that each student can vote only once, the answer would be
