The ratio of the lengths of the sides of a triangle abc is 3: 4: 6. m, n, and k are the midpoints of the sides. perimeter of the △mnk equals 5.2 in. find the length of the sides of the △abc.

Each midsegment is half the length of its corresponding parallel segment, so the perimeter of ∆MNK is half the perimeter of ∆ABC. Then the perimeter of ∆ABC is ...

... 2 × 5.2 in = 10.4 in

The side length ratios total 3+4+6 = 13 "ratio units" (corresponding to the total of side lengths, the perimeter), so the sides are 3/13, 4/13, and 6/13 of the perimeter, respectively. That is, the side lengths are ...

... 3/13 × 10.4 in = 2.4 in

... 4/13 × 10.4 in = 3.2 in

... 6/13 × 10.4 in = 4.8 in
