Answer:

18.5

Step-by-step explanation:

It says

IJ is the midsegment of the triangle. So it divides both adjacent sides in half/at modpoint.

so HF is 10 cm .. half of that is 5 cm

GH is 13 cm.. Half of that is 6.5 cm

now we have IJ = 7 cm given

add all those.. you get 18.5 cm

Answer:

18.5

Step-by-step explanation:

35.

Segment IJ is a midsegment of triangle FGH, so

2HI = 2FI = FH

2HJ = 2JG = GH

FG = 2IJ

Perimeter of triangle IJH = IJ + JH + HI

IJ + JH + HI = 7 + 6.5 + 5 = 18.5
