The perimeter of the larger polygon will have the same ratio to the perimeter of the smaller as the ratio of the corresponding sides. Therefore, the larger polygon will have a perimeter of 30(15/12) = 37.5, or 38 to the justified number of significant digits stated.
10 * 6 = 60 by the time Zach joins so 125-60 = 65 Now 6 (lexie) +7 (zach) = 13 (together) and 65/13 = 5. 6*5 = 30 and 7*5 = 35. 35+30 = 65 Your answer is 5.
