Final answer:
To find the length of each side of the triangle with the given ratio, multiply each ratio value by the perimeter divided by the total ratio value.
Step-by-step explanation:
To find the length of each side of the triangle, we first need to find the total of the ratio values (12 + 14 + 9 = 35). Then, we can find the length of each side by multiplying the ratio value by the perimeter of the triangle and dividing by the total ratio value.
Side 1 = (12/35) * 245 = 84 inches
Side 2 = (14/35) * 245 = 98 inches
Side 3 = (9/35) * 245 = 63 inches
